Rank 1 is the lowest business-strike mintage in the series. Mintage is what the Mint produced, not what survives. These circulated through the 1920s and 1930s and were melted for their silver later, none of it recorded by date. On the 1916-1924 issues the date itself wore away, so a large share of what survives cannot be attributed to a year at all.
Reading the figure
It is the largest of the 12 San Francisco issues in the series. Of the 32,692,800 struck across all mints in 1918, this issue accounts for 34%. That is 1.5 times the Denver figure for the same year. The 1918 split ran Philadelphia 14,240,000, San Francisco 11,072,000 and Denver 7,380,800. The series median is 3,586,400, so this issue is more than twice as numerous as a typical date.
Every sentence above is computed from the mintage table on this page, not asserted separately.
About this figure
The 1918/7-S overdate is included in this total. It was never reported separately, so it is documented here as a variety rather than given a mintage of its own.
Scarcity tier
Common date
Assigned from reported mintage alone: under 750,000 is a key date, under 2,500,000 is a semi-key.
This is a reproducible label derived from the mintage column, not a market valuation and not a Coin Curator price opinion. The same thresholds apply to every series on this site. Several dates are far harder or far easier to obtain than their mintage implies; where that is true, it is stated above.
Documented varieties
1918/7-S Overdate
A 1918 die punched over a 1917 one, with the 7 visible beneath the 8. One of the most valuable coins of the series and heavily counterfeited.
Widely recognised varieties only. The VAM reference catalogs thousands of die marriages across these series; the absence of a variety here does not mean none is documented elsewhere.
The date wears off the early issues. On the 1916-1924 quarters the date sits raised on a pedestal at the base of the obverse, exposed to every hand that touched the coin. Read the full note on the series page.
What to check before buying
Specific to the 1918-S:
- 1The overdate is faked and is also confused with die deterioration around the date. Insist on the attribution appearing on the certification label rather than in the listing text.
- 2Confirm the date is genuinely struck and legible rather than restored with acid, which leaves a dull pitted patch around the digits. The grading services will not certify an acid-treated coin.
And for any certified coin
Verify the certification number on the grading service’s own lookup rather than from a photograph of the label, match the listing images to the certification record including grade and any variety attribution, look for cleaning, compare the mintmark against published photographs of the genuine issue, and read the return policy before buying. The grading guide covers each of these in full.
Coin Curator does not grade, authenticate, or appraise coins, and publishes no price or population data. These are verification steps, not a valuation.
