well,, getting back to dies..

This is a US die... From the 1930s... The cartouche is U shaped on the die. But when on the rounding mandrel it will be flat!

So we have 19 on one side and 3 on the other. Depending on the year the final number I think would be cut on to the working die... Old and in good condition... These were usually stored in very heavy cardboard box or usually wood with the corresponding number on the outside of box..
