Can't post a picture right now, but maybe someone will recognize this description: Copper, probably, defenite coin shaped but thicker { like 2 quarters stacked}, has the number 4S on it. That's about it for now. Any ideas?
well here's a lousy { really lousy } picture taken from a cell phone. It is the diameter of a quarter, about twice as thick, says " 4 S " on the front and a tiny little "t" on the back.
There is an apotechary weight unit called 'scruple' It weighs 1,296 grams so if your copper disc is bit over five grams maybe it is an apotechary weight.
Whatever it actually is it looks like that 4s is hand stamped so this probably isn't a factory made object.
