I found while looking through change a while back, I seem to think I have seen something like it in a mint set.I believe it was from 60's or 70's But googling it did me no good. Is it worth a cent? Sorry no pics but I am sure most would know what I am talking about. JON
They were part of the US mint sets from 84-88 or 89. There is also a D. Both were minted on US cent planchets. They're interesting but aren't worth much
