Hello Everyone. What's up with this penny? I acquired it within a larger collection of mixed denominatuon coins last year. I don't know if its been plated or altered in any way but wanted to run it by you all. I weighed it and it fluctuates between 2.48 and 2.50 grams, it seems to prefer 2.5 on average. Given all the penny types/varieties of the 82/83 years I thought it a good idea to check. Thanks for the help.
Looks like a high school experiment. There are brassy cents, 97' and 98', possibly even other years. That is were there was too much zinc in the copper plating.
