Silver planchets for the series will be supplied by Sunshine Minting. These coins were struck in both copper and nickel planchets. The punched disks are first known as "type-1 blanks (or planchets)". Those rods become the dies which strike planchets making them into coins. Throughout 1863, the coins were struck on planchets of varying thickness. The vast majority of medieval coins were cold struck; the planchets were not heated. A few copper cents from 1943 were produced from 1942 planchets remaining in the bins. As production was inexact, many planchets intended for silver dollars were overweight. By March, the Mint had run out of planchets, which temporarily halted striking. After the war ended in 1815, the mint wasted no time in ordering new planchets. It is believed that this was done to correct the weight of underweight planchets. The planchets were usually hot prior to striking. Planchets subsequently struck by the clashed dies receive the distorted image.
