Old Paper Currency & Notes: A Guide

Large-size and small-size notes

United States paper currency changed physical size in 1928. Notes issued before that redesign, commonly called large-size notes, are noticeably bigger than modern bills; notes from 1928 onward, small-size notes, match the size of currency still issued today. That size alone is a fast, reliable first clue to roughly how old a note is before you read anything else printed on it.

Within both size categories, the United States issued several distinct kinds of notes at different points, each identifiable by the wording across the top of the note and the color of its Treasury seal, and knowing which kind you are holding is the necessary first step before condition or value mean anything.

The note types you will encounter

Silver certificates, identified by a blue seal, were redeemable in silver and circulated for much of the nineteenth and twentieth centuries before that redemption ended. United States Notes, also called legal tender notes and marked with a red seal, were issued directly by the Treasury rather than through the Federal Reserve system. Federal Reserve Notes, with a green seal, are the type still issued today and make up the great majority of small-size currency in circulation from the mid-twentieth century onward.

National Bank Notes, distinguished by the name of the specific chartered local bank printed on the note itself along with a brown seal, were issued by thousands of individual banks across the country under federal authorization rather than by the Treasury directly, which makes the issuing bank part of what collectors research. Gold certificates, with a gold or orange seal, existed before private gold ownership was restricted in the 1930s and are a distinct, earlier category collectors seek out separately.

Star notes and fancy serial numbers

Every note carries a serial number, and when a note in a printing run was damaged or misprinted, the replacement note printed to keep the run's count correct carries a star symbol within its serial number instead of the usual prefix or suffix letter. These star notes were produced in smaller numbers than the regular run they replaced, which is why collectors track them as a distinct, and generally scarcer, category within the same type and series.

Separately from star notes, collectors also seek out fancy serial numbers: low numbers near the start of a run, numbers with repeating or matching digits, ladders where the digits run in sequence, and similar patterns that have nothing to do with how the note was printed and everything to do with how collectible the number itself looks.

Grading paper money and checking its value

Paper currency has its own grading vocabulary, running from heavily circulated grades such as Good and Fine through Very Fine and Extremely Fine, up to About Uncirculated and Uncirculated, sometimes further distinguished as Gem for an exceptional survivor. Graders look at folds and creases, corner wear, staining, tears, pinholes, and how well the note is centered within its margins, all of which behave differently on paper than the wear patterns collectors read on metal coins.

Value depends on the same combination that governs coins, expressed in paper terms: the type of note, its series year, the pair of signatures printed on it, which changed periodically and are catalogued individually, its condition, and how rare that specific combination is. A standard reference catalog for United States paper money, organized by Friedberg number, the standard numbering system collectors and dealers use to identify note types precisely, is the right starting point for checking a specific note, the same role the Red Book plays for coins. This page sits alongside the wider guide to coins and currency, and the identification, grading, and key-date logic covered there carries over to notes with only the vocabulary changed.

Handling and storing old notes

Paper is far less forgiving than metal. A single hard fold across a note can drop it a full grade or more, and folds accumulate quickly if a note is carried, rubber-banded with others, or stored loose in a drawer. Handle notes by the edges, keep them flat, and never use tape, glue, or a stapler to repair a tear; every one of those fixes is itself damage in the eyes of a grader or a knowledgeable buyer, and none of them can be undone.

Inert plastic holders made for currency, sold as archival sleeves or note holders, protect a note from handling and humidity without altering it. Avoid ordinary envelopes and plastic sleeves not rated for archival use, since acidic paper and certain plastics degrade a note over years of contact. As with coins, a note is worth protecting from the moment you think it might matter, not only after you have confirmed that it does.

Value information here is general, educational guidance about how paper currency is typically evaluated, not an appraisal or an offer to buy or sell. Check a specific note against a current specialty catalog and recent realized auction results before drawing any conclusion.

Common questions

How can I tell roughly how old a note is at a glance?

Check its physical size first. Large-size notes predate the 1928 redesign and small-size notes match the currency size still used today. From there, the seal color and the wording across the top identify the specific note type, which narrows the date range further.

Does a low serial number make a note valuable?

It can add collector interest, along with star notes and other fancy serial number patterns, but it is one factor among several. Type, series, signatures, and condition still set the baseline value, and a fancy serial number adds a premium on top of that rather than replacing it.
