About this coinHistory

Mintage for 1851 reached 781,000 half dimes at Philadelphia. The Act of March 3, 1851, authorized the three-cent silver (trime) to facilitate postage stamp purchases, though the new denomination did not directly compete with the half dime. The 1851 was a busy year for the Philadelphia Mint, which was producing the new trimes alongside the established silver denominations and the expanding gold coinage driven by California bullion.

The 1851 is a common date in the Seated Liberty half dime series. Circulated examples are plentiful, and Uncirculated coins are available through normal market channels. Die varieties exist but do not significantly affect the date's overall market pricing.
