- I read in the latest Coin World (April 19, 2004; page 18) that the
anvil die in a Schuler press is stationary while the collar moves up
and down. This is the reverse of the Bliss press, which is reported
to have an anvil die that moves up and down on a cam while the collar
At least the collar still surrounds the neck of the anvil die, so
collar marks remain a reliable sign of which die was the anvil die.
There have been many makes and models of presses used over the years
(Bliss, Graebner, Schuler, Columbia) and mint workers themselves
sometimes make modifications to those models.
