1870 Proof Two Cent Pattern - J-791

Coin Details

Description

A copper striking from the same die pair as J-790, this two-cent pattern features the shield obverse bearing IN GOD WE TRUST and the wreath reverse with denomination. Copper was the natural comparison metal for two-cent patterns, as the denomination had been struck in bronze (95% copper) since its inception in 1864. William Barber's copper striking allowed direct visual comparison between the established bronze composition and Linderman's proposed standard silver alloy, highlighting how dramatically different the familiar shield design appeared depending on the metal chosen.

Rarity Notes

R-6 to R-7. Estimated 10-20 examples survive.
