Thanks for the help.
I have just sent an e-mail to the guy who asked me to try to ID/sell his
chips. I asked him for more info(markings, size, construction material,
color, approximate age, possible country of origin, etc.). Maybe Archie
is right and they will turn out to be tiddly-winks. I'll let you know what
I find out.
Thanks again for the help.
