I was going to trash this picture of three items of mine, but thought you might want to see these -- checkers or backgammon pieces, from the old Hunt Co,. that have the same chain link design found on the rim molds of Hunt Co. chips. All are 1/4" thick.

The blue one has 14 links and is 1-3/4" across. The red ones have 12 links and are 1-3/8" across.
