So I just found this in a roll of pennies it looks like it's silver or just shiny I have no idea it weighs 2.32 G there's no front there's no back there's no read at Edge but it looks like this copper in the middle
Did a little research on YouTube it could be a dime and there's a type 1 and a type 2 but it's the same size as a penny
It's called a caliper or micrometer. They're not expensive at Harbor Freight. Good luck. https://www.harborfreight.com/hand-...rs-micrometer/6-in-utility-caliper-63664.html
So that you know. A type 1 is a planchet that was just punched from sheet stock. A type 2 planchet has been run thru the upsetting mill and has raised edges. That looks like a type 2 clad dime planchet except you say that it is the same size as a cent. The weight is right just not the diameter.
