1947 Copper/Nickel/Zinc Penny (Ml)

Thanks all - I did actually ask the XRF owners to humour me and zapped a 1947 penny, a 1989 nickel, a dime, and two of my 1859 pennies (because why not). That's where my original variation estimate came from as far as stats/percentage variations of the machine being used. It is absolutely odd that it is the same weight and dimensions as a normal penny which is why I wanted to see if I could find "the" potential token that the mint was making in that timeframe that it may have been accidentally made with. Otherwise my only thought was a possible non-circulation experiment run in Canada as 1947 was the year that Britain changed over their small silver denominations (six pence for eg) to copper-nickel alloys.

Yes!!!!! Haha and there it is! Where/how did you come across it?

Thermo Fisher is a 40 billion a year NYSE listed company their measurement machines are top notched, back in the old days collectors would make nasty scratches to see if it is plated as this is what seems to happen to this coin. Info from other collectors here have gotten your answer, as other have tried the RCM rarely is helpfull in these inquieres, probably an internal RCM test, another example of a off metal strike

I think it is! I had two readings taken which ranged a bit but came out to about 65 Cu, 30-33 Ni and then the rest tin/zinc.

Lol, just the original coin. Each coin came out to what it should be +- a percent or two.

Thank you for sharing and to everyone for all the info! I plan on sending it to Sean this week for a PGCS slab!
