Banknote condition: how paper is read

Banknotes · 5 September 2026

Coins are read by wear on the high points; paper money is read by folds. A note that has been folded once is a different object from one that never was, and no amount of brightness or clean paper makes up for it. Four things carry the grade: the folds, the corners, the body of the paper and the edges – in that order.

The five levels in plain words

1. As issued. No folds at all, sharp corners, full original crispness. The paper still has the stiffness it left the press with.
2. Almost as issued. One light fold or a single corner bend, otherwise crisp. This is the level most people misjudge – a note can look perfect and still carry one centre fold.
3. Lightly circulated. Two or three folds, corners slightly rounded, paper still has body but not the original snap.
4. Circulated. Multiple folds crossing each other, rounded corners, softened paper, perhaps light soiling along the fold lines.
5. Well worn. Limp paper, dark fold lines, edge splits starting, general dirt. At this level only genuinely scarce notes hold interest.

Why folds outrank everything

A fold breaks the fibres of the paper permanently. It shows as a line under raking light even after the note has been flattened, and it darkens over time as dirt collects along it. That is why flattening a note under a book or with an iron does not raise its grade – it removes the visible crease while leaving the broken fibre, which reads to anyone experienced as a pressed note, a description worse than an honest fold.

The four readings, in order

• Folds. Hold the note flat and tilt it under one light source. Count them; note whether they cross.
• Corners. Sharp, slightly rounded or bumped. Corners go first in a wallet and they cannot be restored.
• Body. Hold the note by one edge – crisp paper stands, tired paper droops. This is the fastest single test there is.
• Edges. Look for nicks, small splits at the end of fold lines and any trimming. A trimmed note is described as trimmed regardless of how clean it looks.

Damage is not wear

• Pinholes and staple holes. Common on notes once held in bundles; recorded separately and visible against the light.
• Writing and stamps. Bank counting marks, dates in pen, cashier initials – all noted, none removable without making it worse.
• Tape and repairs. Any adhesive is worse than the tear it covers; it stains the paper and cannot be reversed.
• Washing and pressing. Both leave the paper flat but lifeless, with a different surface sheen. It reads as processed, not as fresh.
• Rust and foxing. Brown spots from metal contact or damp – active damage that keeps spreading.

Storage that stops the decline

1. Store notes flat and unfolded, in sleeves sized to the note – never folded into a smaller holder.
2. Use inert sleeves, not soft PVC, which marks ink over the years.
3. Keep them dark and dry: light fades the colours and damp buckles the paper.
4. Never stack heavy albums on top of one another; pressure creates its own set of marks.
5. Do not carry "one good note" in a wallet – a day in a pocket costs a level.

What the archive shows

The open archive holds 635 Soviet banknotes, 462 of them dated, from the reforms of the 1920s to the last issue of 1991. Comparing several examples of the same denomination is the practical way to calibrate the readings above – and the 1991 issue is a useful case, because those notes circulated for months rather than decades, so uncreased examples are common, as described in the guide to the banknotes of 1991.
