I had to Google "billon" as I had never heard of that before.

Billon is an alloy of a precious metal with a majority base metal content. It is used chiefly for making coins, medals, and token coins. The word comes from the French bille, which means "log".
Tony, a lot of the medieval silvers I found in Germany were made of billon (pronounced bee-yon), usually about 27% silver or so.
