United States, 2 and 12 Dollar Coin , Proof, 1829

<< >>
United States Mint, Philadelphia. Obverse: Capped head of Liberty facing left, stars around, date below. Reverse: Eagle, motto above, denomination below. This 1829 proof quarter eagle introduces us to a modified coining technique and to a slightly modified design. The coin (and its multiple, the half eagle) would henceforth be struck using a one-piece, "close" collar. Also, a third die whose vertical striations produced the familiar "reeded" edge we still see on coins today.
Striking the quarter and half eagles in a collar resulted in better metal flow and sharper detail. But it also required modest changes in the obverse and reverse designs. The work was carried out by William Kneass. As many as a dozen 1829 proof quarter eagles including this one may exist. Most have been damaged by handling.
