RPM or zinc?

[amnight]

Wanted to know if this is an RPM or zinc. I looked on coppercoins but didn't see it. Thanks!

The weight will verify if it is zinc or not (2.5g). It does look like a plating blister to me though.

Thanks Bob. Also is this blistering behind Lincolns head?

It is indeed- plating blisters can appear as bubbles like on your coin, or as long lines across the coin, aka linear plating blisters.

Plating blisters as noted. We have a page on them here: http://error-ref.com/BlisteredPlating.html

That's interesting... Do you guys know what the tolerance is for the zinc cent? I found one the other day that was a 99 and it weighed 3 grams
