William Barber's "Amazonian" design considered to be one of the most beautiful ever made by the US Mint. This design was issued in sets of the quarter dollar, half dollar and silver dollar in silver, copper and aluminum as above. To view the set, click here.
The Amazonian name dates to the 1890 New York Coin and Stamp auction of the Lorin G. Parmelee collection and was probably given by David Proskey.
It differs from the quarter J1195-J1197/P1335-P1337 and dollar J1205-J1207/P1345-P1347 designs in having an olive branch for peace draped over the shield as there was a criticism that the design was too military. It is likely that this die was made last.
The following examples are confirmed:
1) Rarcoa's Boosel sale, Rogers M Fred-Bowers and Merena 11/95, Stacks 7/08, Simpson-Heritage 4/21 - PCGS64 illustrated above
2) Stacks 10/00, Simpson collection - NGC64/PCGS64 with obverse lamination from 1:30 to 7:30 - illustrated below.
Others possible from Farouk; Kosoff 11/55; Lohr-Cox
Examples were also struck in silver J1200/P1340 and copper J1201/P1341 with the latter often showing a "flattened" dentelle on the obverse at 12:00 caused by scrap adhering to the die.
