(which possibly stands for "South American"). Reverse Design Blank. Metal Brass Size and Shape Round, approximately 46 mm in diameter. There is one small round hole on at the top.

Issurer I.C.C. stands for Isthmian Canal Commission, which was the part of the U.S. government responsible for building the canal. Numbers Issued Only known piece is #973. Rarity Possibly unique.
