Greg, thanks - several others were referring to them as "ceramic" covered. I'm too inexperienced
& am depending on the "pros". I've seen so many
definitions of "chokens" or "colored tokens" that
I have been saying, "chokens, colored tokens,
whatever".
As you know, some are completely coated with
plastic & some are colored tokens with a
surrounding metal band. I do gather that they
all were failures while being used in the machines.
