1910-S Indian Head Half Eagle

Semi-key

A San Francisco issue from the years when the half eagle still moved in ordinary commerce, before production stopped in 1916.

Mintage

Business strikes: 770,200
Mint: San Francisco (S)
Mintage rank: 19 of 24

Rank 1 is the lowest business-strike mintage in the series. Mintage is what the Mint produced, not what survives. Gold coin was recalled in 1933 under Executive Order 6102 and the Treasury melted much of what it held, so survival across this series runs well below the figures below. The 1929 is the extreme case: a six-figure mintage and a genuine rarity.

Reading the figure

Among the 9 San Francisco issues in the series it is the 8th smallest. Of the 1,567,800 struck across all mints in 1910, this issue accounts for 49%. That is 4 times the Denver figure for the same year. The 1910 split ran San Francisco 770,200, Philadelphia 604,000 and Denver 193,600. Series-wide output fell that year: 1,567,800 against 4,382,020 in 1909. In 1910 the coin was struck at Philadelphia, Denver and San Francisco; New Orleans struck none.

Scarcity tier

Semi-key

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.

Grading an incuse design is not like grading any other. The devices on this coin are sunk into the surface rather than raised above it, which is unique to the Indian Head quarter eagle and half eagle among regular United States coins. Read the full note on the series page.

What to check before buying

Nothing about this date calls for a check beyond the ones that apply to any certified 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.

Verify a certification number

Look a 1910-Scertification number up on the service’s own site. A photograph of a label proves nothing.
