Could this be a wrong planchet? The color was so different so I pulled it aside to weigh it. Help on this would be great! Here is a color comparison
Weight is within tolerances. Coins end up discolored all the time for any number of reasons.
The spec range for a cent is 3.11 gms +/- 0.13 gms, so your coin is normal weight
One more for the consensus of 'within range'.... Cheers, RickO
Grind it down a little further and it'll be 2.5 grams.
They do get lighter as they wear down
