What Does a Grade 64 Mean?
Choice Uncirculated

A 64 is the top of the Choice Uncirculated tier — a strong, fully uncirculated note sitting right at the boundary of Gem. It's the grade collectors debate most, the one that almost crossed a threshold but didn't quite. Here's exactly what that means, and why it still matters.

What a Grade 64 Note Looks Like

A Choice Uncirculated 64 is a fully uncirculated note with solid eye appeal — no folds, no creases, original paper body, and corners that are sharp and intact. In hand, it looks like a quality example that has been well preserved. Color is good to strong, printing is clear, and there is no evidence of circulation handling of any kind.

What separates a 64 from a 65 Gem is the accumulation of minor imperfections that, taken together, prevent the note from achieving Gem-level eye appeal. This might be a more readily visible counting flick on one surface — not severe, but noticeable without magnification. It could be centering that is clearly off in one direction, leaving an uneven margin that stands out. Or it might be a combination of two small factors — a light surface mark and slightly soft paper feel — that individually would be borderline but together tip the scale. No single flaw is dramatic. The 64 simply has one more minor imperfection than a 65 allows, or the same imperfections expressed slightly more noticeably.

Quick takeaway

A 64 is a legitimate, fully uncirculated note that belongs in any working collection. It sits just below the Gem threshold — not because anything is wrong with it, but because the bar for "Gem" is genuinely high. For budget-conscious collectors or those building across a wide series, a 64 is often the smartest acquisition at the uncirculated level.

The most contested grade on the scale

Ask experienced collectors which grade generates the most debate, and many will say 64. It sits exactly at the Gem threshold — close enough that submitters frequently expect a 65 and receive a 64, or vice versa. The difference between a 64 and a 65 is real, but it is also the narrowest gap on the entire uncirculated scale. Two graders looking at the same note on the same day could reasonably land on either side. That subjectivity is baked into the grade, and understanding it helps calibrate your expectations before submitting — and before buying.

Grading Criteria Breakdown

Graders evaluate three primary factors when assigning a grade in the 63–70 range. At Grade 64, here's where a note typically lands on each:

Folds & Creases
None
No folds or creases permitted at any uncirculated grade. A single light fold ends any conversation about uncirculated status, regardless of how strong the rest of the note is.
Paper Quality
Good Body
Original body largely intact. The note holds its structure, though it may feel very slightly softer than a 65 due to subtle original handling at point of issue.
Eye Appeal
Good to Strong
Solid overall presentation with one or more minor imperfections visible without magnification — a counting flick, centering variance, or slight surface mark — that collectively prevent Gem designation.

One important nuance at the 64 level: unlike the grades above it, where a single specific detail often explains the grade, a 64 can result from several different combinations of minor factors. A note with excellent centering and bold color can grade 64 because of a somewhat more visible surface mark. A note with immaculate surfaces can grade 64 because its centering is noticeably off. The grade reflects the aggregate — the sum of the note's presentation — rather than any one definitive flaw. This is part of what makes 64 the most nuanced grade to evaluate and the hardest to predict before submission.

How a Grade 64 Affects Value

The 64 occupies a practical, accessible tier in the market. Notes grading 64 trade regularly at auction and through dealers, and prices are generally well-established for most series. The gap in price between a 63 and a 64 is modest — typically 10 to 20 percent — while the gap between a 64 and a 65 Gem can be more pronounced, especially for series where condition-conscious collectors are active.

Grade 62
Baseline
Grade 63
+10–15%
Grade 64
+10–20%
Grade 65
+20–40%
Grade 66
+30–50%
Grade 67+
Market premium

Important caveat: These are relative multiples, not absolute prices. A common series note in 64 might sell for $20–$40. A scarce or popular series note in 64 might bring considerably more. The grade multiplies whatever inherent value the note carries — series, date, denomination, and signature variety all matter. Always check the PMG population report and recent auction results for your specific note before drawing conclusions.

One dynamic worth understanding: for collectors who submit their own notes, the 64-to-65 boundary is where resubmission decisions get complicated. A strong 64 — one that looks like it might have crossed the line — is sometimes worth resubmitting, particularly for valuable notes where the price difference between grades is significant. But for common series notes, the cost of resubmission often exceeds the value gained from a one-point upgrade. Knowing which side of that calculation you're on requires checking the population report first.

Grade 64 vs. Nearby Grades: What's the Real Difference?

The 64 is the most crowded grade on the uncirculated scale — notes cluster here because it represents the realistic outcome for a large proportion of well-preserved uncirculated survivors that just missed Gem. Here's how it compares to the grades around it:

Grade Name Difference from 64 Availability
62 Uncirculated Two steps below, with more apparent minor imperfections — visible surface marks, clearly off-center margins, or paper that shows more evidence of original handling. Solid uncirculated notes, but noticeably below Choice level. Common
63 Choice Uncirculated One step below 64, with slightly more numerous or noticeable imperfections. Still a fully uncirculated note with good eye appeal — the difference from 64 is subtle but consistent. Common
64 Choice Unc (this grade) The top of the Choice tier. Strong uncirculated note with minor imperfections that — in aggregate — prevent Gem designation. The most contested boundary on the uncirculated scale. Less Common
65 Gem Uncirculated Crosses the Gem threshold. The same types of imperfections are present, but fewer or smaller — the overall impression clears the bar for genuine Gem eye appeal. Uncommon
66+ Gem / Superb Gem Unc Upper Gem and Superb Gem territory. Imperfections become progressively smaller and fewer, with rapidly increasing scarcity and price premiums at each step. Uncommon – Rare

The most practical takeaway: a 64 is a fully respectable uncirculated note, and there is no shame in a 64 holder. The grade reflects a note that has been honestly evaluated against a genuine standard — not a note that failed, but a note that landed where it landed. For series-builders working across many dates or varieties, a consistent set of 64s is a meaningful achievement. And for those chasing upgrades, a strong 64 is exactly the kind of note worth watching for resubmission opportunities when populations are thin at 65.
