The popular trime design executed by Franklin Peale from designs by Longacre. The obverse design was apparently copied from the design used on the 1836 gold dollar pattern J67-J71/P70-P74 originally created by Christian Gobrecht.
Judd states that restrikes of this were made but are proabably not distinguishable today.

The example above, showing just the reverse, appears to be a mint error caused when 2 planchets were fed into the press. It is ex H Chapman 6/1908 (Taylor Windle sale) lot 1308, Brand (journal #44209), Kelly 2/13/41 B.G. Johnson invoice, Bolt, Numismatics Ltd, Bowers and Merena's 6/96 and Heritage 9/97 and 11/03 sales. Does anyone have the piece showing just the reverse ?
