Unique, "EB on Breast"
1787 Brasher Doubloon from
The Gold Rush Collection
This is an engineering drawing (frontal
view) of the toggle-joint steam coining press designed
by Franklin Peale and first used at the Philadelphia Mint
in 1836. Presses of this type (believed to be the "small
size") were used at the Dahlonega and Charlotte Mints.
Power to turn the press was supplied by a belt from the
steam engine. The detail at the extreme upper left is
of the toggle joint.
