The Grade Scale
Every grade, explained
GRADENIK reports on a 0.5 to 10.0 scale, in the same tenth-point increments used across the collecting world. Here's what each range means.
What We Cover
The 28-point inspection
This is the exact order GRADENIK inspects a comic in-app, from the very first question to the last. Tap any factor to read why it matters and what it looks like in hand.
01 Physical Completeness +
Does your comic have its full cover and back cover, or is a major part of the book missing or cut out entirely?
Why it matters: This is asked first because it can override almost everything else. A comic missing its cover, reduced to loose pages, or missing story content from the inside can't be meaningfully assessed on things like reflectivity or stamps in the same way.
This is different from wear or tears — it's about whether the physical book is actually whole. A worn but complete comic, a comic reduced to bare pages, and a comic with a panel or coupon deliberately cut from an interior page are all fundamentally different situations, so this gets asked on its own, separately from general handling wear.
02 Wear +
How much general handling wear does the comic show?
Why it matters: This is the broadest read on the book's life — how much it's been picked up, read, and handled sets the outer boundary for everything else.
Comics are printed on paper never meant to survive decades of handling. Every read, every time it's slid in or out of a longbox, leaves microscopic wear that compounds over the years. This factor captures that cumulative story before we even look at anything specific like the spine or staples.
03 Ink Colour Reflectivity +
How much shine or reflectivity does the cover ink still have?
Why it matters: This tells you how much of the original printing quality survives — once the ink loses its reflective sheen, it never comes back.
Fresh comic ink has a slight gloss that catches the light. Over time, handling and UV exposure wear that sheen down to a flat, dull surface. It's a one-way process, and because it affects the entire cover rather than one small area, it can weigh heavily on eye appeal even when nothing is physically torn or missing.
04 Paper Creases (Cover) +
Are there any creases on the cover?
Why it matters: A crease is a permanent fold in the paper fibers — unlike surface wear, it can't be smoothed back out.
Once cover stock is folded, the fibers along that line are physically broken, not just bent. Whether it breaks the printed color (leaving a visible white line) or not makes a big difference in how noticeable — and how permanent-looking — the damage is.
05 Paper Corners +
What's the condition of the corners?
Why it matters: Corners are the first thing to show wear on any book — they take the most contact from storage and handling.
Sharp, printed corners are how the book left the factory. Every time a comic is pulled from a stack, slid into a bag, or handled without care, the corners take the impact first — rounding, blunting, or folding over long before anything else on the book shows wear.
06 Stamps +
Tick every mark that applies to this cover — a book can have more than one (for example, a store stamp and a sticker together).
Why it matters: These weren't applied by the reader, so they're treated differently to personal writing — but not all marks are equal. A stamp is printed on; a sticker is stuck on and often damages the surface underneath when it's ever removed. If more than one applies, the worst one governs.
Before barcodes, newsstands and comic shops tracked inventory by stamping arrival dates or a store name straight onto the cover, or marking the price by hand or with an ink stamp. Provided it doesn't sit over the artwork, this is treated as minor. Stickers are a different story — the adhesive can pull ink off the cover or leave residue behind even years after being peeled, so they're capped much lower.
07 Centrefold +
Open the book flat to the centre — how secure is the centrefold (the middle, stapled pages)?
Why it matters: The centrefold is the structural heart of the book — if it's coming loose, the whole comic starts to lose its shape.
The centrefold carries the weight of every page around it. Once it starts separating from the staples, the pages on either side lose support too, which is why a loose centrefold tends to bring other problems (staple stress, cover looseness) along with it.
08 Centrefold Detachment — Repairable or Torn +
Since the centrefold is detached, is the paper itself torn at that point, or is it a clean separation that could be professionally reattached?
Why it matters: A clean detachment is a cosmetic/structural repair issue — the paper is fine, it's just come away from the staples. A tear means actual paper has been damaged or lost, which is graded far more severely.
This distinction matters a lot for value: a cleanly detached wrap can still grade respectably, since nothing is actually missing or damaged. A torn centrefold is treated the same as any other interior tear of that size.
09 Staple Alignment +
With the book still open to the centre, are the staples generally centred, or noticeably off?
Why it matters: This is a factory quality marker — it reflects how carefully the book was bound, not how it's been treated since. Any actual stress or tearing this may have caused is captured separately, so this factor is judged on position alone.
Staples were driven by fast-moving machinery on the print line, and alignment could drift. A slightly off-center staple is common and mostly cosmetic. Even a noticeably crooked staple, on its own, doesn't threaten the book's structure — that risk only shows up if it's also caused visible stress or tearing, which are judged separately under Staple Stress and Staple Tears.
10 Staple Tears +
From the centre, is there any tearing in the paper around the staples?
Why it matters: This is where structural stress shows up first — the paper around a staple is a small, high-stress point.
Every time a comic is opened, the staple holes take a bit of strain. Over years of handling this can turn into small radiating tears. A single slight tear barely affects anything; several accumulated tears suggest the book has been opened and closed a lot, or handled roughly.
11 Staple Stress +
From the centre, is the paper around the staples stretched or whitened, even without a visible tear?
Why it matters: This is the stage before an actual staple tear — catching it separately gives a more accurate picture of a book that hasn't torn yet but is under strain.
Before paper actually tears at a staple hole, it often stretches and whitens under repeated stress, the same way fabric thins before it splits. Spotting this early is a good indicator of how much more handling the book can safely take.
12 Staple Colour +
From the centre, what's the condition of the staple colour — any rust?
Why it matters: Rust isn't just cosmetic — it signals moisture exposure at some point in the book's life, and it can migrate outward into the surrounding paper.
Staples are plain metal, and metal reacts with humidity in the air over time. Even books stored carefully can develop light surface rust after enough decades. The concern isn't just how it looks — rust can leave stains on the pages next to it, which is captured separately under staple migration.
13 Staple Migration +
Still from the centre, has any staple rust spread (migrated) onto the surrounding paper?
Why it matters: This measures whether staple rust has actually started damaging the paper around it, not just the staple itself.
Rust migration happens when moisture carries iron oxide from the staple into the adjacent paper fibers, leaving a reddish-brown stain that spreads outward over time. It's a slow process, so its presence usually indicates a book has been in less-than-ideal storage conditions for a long time.
14 Spine Ticks +
Now looking at the spine from the outside — are there any small nicks that haven't opened into full splits?
Why it matters: Ticks are the earliest visible sign of spine stress — catching them here, separate from full splits, gives a more accurate read on a book that's otherwise clean.
Every time the spine flexes, tiny surface fibers can nick before the fold ever actually separates. Whether a tick breaks through the printed colour layer matters a lot — a colour-breaking tick means the damage has gone past the surface ink, which is treated more seriously than one that hasn't.
15 Spine Stress Lines +
From the outside of the spine, is there visible strain — lines or whitening before an actual tick or split?
Why it matters: Stress lines are the warning sign that comes before ticks and splits. Catching this separately helps explain why a book might be more fragile than its current tick/split count suggests.
Repeated flexing weakens the paper fibers along the spine fold before they actually separate. That strain often shows up first as faint whitened lines or a slightly rippled look, well before an actual tick or split appears.
16 Spine Roll +
Still looking from the outside, does the book show any spine roll, from being stored or read rolled up?
Why it matters: Spine roll is its own kind of damage, independent of ticks or splits — it comes from how the book's been stored or handled, not from ordinary page-turning wear.
When a comic is rolled up (in a back pocket, a tube, or just leaned awkwardly on a shelf for years), the spine takes on a permanent curve instead of lying flat. It's a structural, not cosmetic, issue — a rolled spine puts ongoing stress on the whole binding.
17 Spine Splits +
From the outside of the spine, is there any splitting, and how long?
Why it matters: The spine takes constant flexing stress every time the book is opened, so this is usually the single most telling structural factor.
The spine is the fold line the entire book pivots on. Repeated opening stresses that fold until the paper fibers begin to separate — first as small stress lines, then visible ticks, then splits that grow in length. Whether a split breaks the printed color matters too, since that indicates the tear has gone deeper than the surface layer.
18 Cover Attachment +
How securely is the cover attached to the rest of the book?
Why it matters: This is about whether the cover is still doing its job of holding the book together, separate from how worn the cover itself looks.
The cover takes the most physical stress of any part of the comic — it's what gets gripped, bent, and slid around. Once it starts pulling away from the staples, that stress transfers directly to the interior pages, accelerating wear everywhere else.
19 Cover Detachment — Repairable or Torn +
Since the cover is detached, is the paper itself torn at that point, or is it a clean separation that could be professionally reattached?
Why it matters: A clean detachment is a cosmetic/structural repair issue — the paper is fine, it's just come away from the staples. A tear means actual paper has been damaged or lost, which is graded far more severely.
This distinction matters a lot for value: a cleanly detached cover can still grade respectably, since nothing is actually missing or damaged. A torn cover is treated the same as any other cover tear of that size.
20 Interior Tears +
Are there any tears on the interior pages?
Why it matters: Interior tears affect readability and structural integrity, separate from anything happening on the cover.
Interior paper is thinner and more fragile than the cover stock, so tears here often happen from page-turning stress rather than outside damage. Graders judge this qualitatively rather than counting an exact number — a few small tears barely register, but as they become more noticeable or numerous, the cumulative effect on eye appeal grows. Longer tears (¼" and up) are treated more seriously regardless of how many there are.
21 Paper Colour +
What colour has the interior paper aged to?
Why it matters: Paper colour is one of the most reliable indicators of age and storage conditions, and it's very hard to fake or reverse.
Comic paper contains acidic wood pulp that yellows and browns as it oxidizes over time — the same reason old newspapers turn brown. How fast this happens depends heavily on storage: books kept away from light, heat, and humidity stay whiter far longer than ones left in damp basements or hot attics.
22 Paper Texture +
Is the paper still supple, or has it become brittle?
Why it matters: This is a measure of structural safety, not just appearance — brittle paper can crack or crumble just from being handled.
As the acidic compounds in old paper break down further, the cellulose fibers lose flexibility. Supple paper bends without damage; brittle paper snaps or flakes at the edges. Once a comic reaches true brittleness, even careful reading risks permanent damage, which is why this factor caps the grade so aggressively.
23 Paper Smell +
Does the book have any acidic or chemical odour?
Why it matters: Smell is often the earliest warning sign of paper breaking down chemically, even before you can see or feel a difference. A mild, musty age smell is treated very differently from a sharp chemical smell that suggests active instability.
As old paper degrades, it releases volatile organic compounds — a musty or slightly acidic smell most collectors recognize instantly, and on its own this is a fairly mild defect. A sharper chemical odour, like a chlorine-type smell, is a different story — it usually points to some kind of chemical exposure or treatment and is treated far more seriously, since it suggests the paper's condition is actively unstable rather than just old.
24 Staining +
Is there any staining, foxing, or water damage anywhere on the comic?
Why it matters: Staining is its own distinct defect category from stamps or ink — it's discoloration soaked into the paper itself, whether from water, age-related foxing, or mold, rather than something sitting on the surface.
Foxing (small brown age spots from dormant mold activated by humidity) is the most common form and is often unavoidable on vintage books. Water staining is more serious since it usually comes with rippling, and mold or mildew is treated most seriously of all since it actively continues to weaken the paper over time.
25 Distortion +
Does the book show any warping, rippling, or printing misalignment (miswrap)?
Why it matters: Distortion covers defects that change the book's shape or alignment without any paper actually being lost — usually from printing issues or moisture exposure during storage.
Most distortion originates at the printer (miswrap, off-register printing) or from humidity causing paper fibers to expand and contract unevenly (rippling, warping). A little of this is common and often barely affects eye appeal, but pronounced warping or a badly miswrapped cover changes how the whole book presents.
26 Bindery Defects +
Are there any factory bindery defects, like miswrapping or trimming errors from printing?
Why it matters: These happened at the printing plant, not from handling, so they're judged on their own terms rather than blamed on wear and tear.
Comics were mass-produced fast and cheap, so factory mistakes were common — off-center staples, a miswrapped signature, uneven trimming. A little of this is expected and doesn't hurt much. It's when several bindery issues stack up on one copy that it starts to meaningfully affect the grade.
27 Missing Pieces +
Is the comic missing any physical pieces of paper from the cover?
Why it matters: This is different from tearing — it's about material that's actually gone from the cover, which can never be restored without professional intervention.
Small missing chunks usually happen when a stuck cover is pulled apart, or a torn piece eventually falls away entirely. The size of what's missing matters a great deal — a tiny corner chip is a very different story to a missing quarter of the front cover.
28 Cover Tears +
Does the cover have any tears? If so, how long is the longest one?
Why it matters: A tear is different from missing material — the paper is split but everything is still there, which matters for how it's graded and whether it can ever be addressed.
Tears are one of the most common defects in real collections, usually from a rough removal from a bag or a snag on a longbox divider. Length matters far more than the exact cause — a short tear is a cosmetic flaw, a long one becomes a structural concern for the whole cover.
