What a Grade 55 Note Looks Like
An About Uncirculated 55 note is visually striking. At a glance it looks nearly new — the paper has clear body, the colors are bright, all printing detail is sharp, and the margins are full. What keeps it from a 58 or higher is a single more significant fold, or two to three light corner folds that cross the design. The fold is there, and it is honest, but the rest of the note is essentially uncirculated.
A 55 can also result from a single harder vertical fold — more set than what a 58 will accept — or from a horizontal fold, which spans the length of the note and is considered a heavier type of fold relative to a short vertical. In either case, the note reads as "almost new" to the eye: good stiffness, minimal wear to surfaces, sharp corners or only lightly touched ones, and nothing dirty or faded.
The 55 is a grade collectors genuinely seek. It sits at the top of the accessible AU range, offering near-new quality without the premium associated with a 58. For series where 58s are scarce or priced aggressively, a 55 is often the most cost-efficient way to own a clearly AU example.
A 55 is a "one clear fold" grade — or the equivalent in light corner fold evidence. Near-new paper body, sharp design, and bright surfaces. The fold is honest and visible but is not accompanied by heavy handling or additional crease damage.
Grading Criteria Breakdown
At AU 55, graders are looking at fold evidence plus the overall handling level. The note earns 55 rather than 53 because the folds present are lighter — not the two hard verticals typical of 53. It earns 55 rather than 58 because the fold is more prominent than a single light corner fold or one very light vertical.
EPQ 55s are common and highly desirable. Because the fold evidence at this grade is minimal, many notes that grade 55 do so on original, unaltered paper — meaning they qualify for the Exceptional Paper Quality designation. A non-EPQ 55 is typically a note that has been pressed to reduce the appearance of a harder fold. The distinction matters to sophisticated collectors and affects resale value meaningfully.
How About Uncirculated 55 Affects Value
Grade 55 commands a genuine premium over lower AU numbers for most series. Collectors who want "AU quality" in their set — a note that looks near-new and has the paper body to prove it — typically target 55 as their minimum for higher-end purchases. It is the grade where the note starts to look truly exceptional to non-specialists as well as experienced collectors.
The jump from 55 to 58 in price is often surprisingly modest for common issues but can be significant for scarcer ones. If the budget allows, pushing to a 58 is worthwhile — but a 55 EPQ is nearly as compelling a note to display and considerably more accessible in price.
Grade 55 vs. Nearby Grades: What's the Real Difference?
The 53–55–58 range is where fold weight and fold count interact most precisely. A 53 has two hard vertical folds — the same count as some 55s but heavier. A 55 has lighter folds or just one fold. A 58 reduces fold evidence further still: a single vertical fold that crosses the design, or one to two light corner folds. The step from 55 to 58 is smaller than it looks but costs more than it should for common issues — which is exactly why many collectors find 55 to be the sweet spot of the AU range.
| Grade | Name | How It Compares to 55 | Collector Feel |
|---|---|---|---|
| 50 | About Uncirculated | Two heavier folds or a horizontal + vertical combination with significant handling. Clearly more fold evidence than a 55. | Entry AU |
| 53 | About Uncirculated | Two hard vertical folds or a single horizontal fold — heavier than the fold evidence on a 55. Same AU paper quality otherwise. | Mid AU |
| 55 | About Uncirculated (this grade) | One fold or two to three light corner folds. Near-new paper body with minimal handling. The strongest AU grade before the Choice tier begins at 58. | Strong AU |
| 58 | Ch. About Uncirculated | A single vertical fold through the design, or one to two light corner folds. Fold evidence is lighter and more minimal than a 55. | Near-new AU |
| 60–64 | Uncirculated | No folds through the design. Any issues are handling-only: corner tips, counting marks, centering. A fully different category. | Uncirculated |
The practical takeaway: an AU 55 is one of the most satisfying grades in the paper money market — high enough to be genuinely impressive, accessible enough to be achievable for most budgets. The fold is there, but so is everything else that makes a note desirable.
