How to make Coins

1. Melting

The metal used to make coins is melted in an electric furnace to make metal blocks called “ingots.”

2. Rolling

The ingots are rolled out into sheets of the right thickness for coins, then coiled up.

3. Stamping out (Blanking)

Round coin shapes are stamped out of the rolled-out metal sheets. These pieces are called “blanks.”

4. Edging

A raised border is made around the edge of the blanks to make the design stand out more.

5. Coining and Inspecting

After the patterns have been stamped on the front and back (the ridges around the edge are made at the same time), the coins are inspected, and any that are damaged or unusable for other reasons are removed.
