| Before
the introduction of the steam powered coining press
in 1836, coins in the United States of America were
made on screw presses. Men and animals provided the
energy. In the nation's very early years oxen and horses
helped operate the presses. Later on the power came
from men alone. |

It
took three (or more) men to operate a screw press, some
on each end of a weighted iron bar and another man seated
in front of the press. The seated man would insert planchets
and remove the finished coins. The other men would tug on
leather straps attached to the iron bar. The bar was attached
to a heavy iron screw which drove an upper die down towards
a lower one when the men on one side of the bar pulled it
towards them. Then, when the men on the other side tugged
on the bar, the screw and upper die were raised and the
seated man would remove the finished coin. A good team of
coiners could turn out several dozen small coins per minute.
