1871 Proof Double Eagle Pattern - J-1178

Coin Details

Description

Closing the 1871 Trade Dollar era pattern series with the largest denomination in aluminum, J-1178 is one of the most physically remarkable coins in all of American numismatics. An aluminum double eagle, at the full diameter of a $20 gold piece but weighing barely more than a production dime, is an object of pure numismatic wonder. The piece serves as the ultimate expression of the Trade Dollar era's ambitious metallurgical experimentation, testing even the most impractical compositional extreme at the highest denomination.

Rarity Notes

R-7 to R-8. Very rare, approximately 3-8 examples known.
