The so-called Amazonian design because of the similar reverse copied from William Barber's quarter, half dollar and dollar patterns of this year. It is the only uniform design ever made for all six denominations. To view the entire set, click here. It is also the only pattern $3.00 gold design.
This is one of the most famous of all pattern designs.
It was made in the following combinations:
J1235/P1377 in gold. The entire set is unique in gold. This particular coin is ex Woodin, Granberg, Newcomer, Col Green, Farouk, Wilkison, Paramount, A-Mark, Leidman, 81 ANA, 83 ANA, Greg Holloway, Superior 10/90, Trompeter, Southern collection, Simpson collection.
It is likely that Woodin got these from A.L. Snowden
for "returning" the 2 gold half unions to him which were then placed back in the Mint cabinet. For more on that, click here.
It is also likely that Col Green owned this as the half eagle and eagle appear in Stacks photographic library - regrettably no $3 gold coins were included in the library.
J1236/P1378 in copper. About a dozen are known, several of which have been gilted.
J1237/P1379 in aluminum. Only 3 are known as follows:
