I found this penny in some change today an you can see 2008 but it is very light and the lib is missing in liberty and in the words in God we trust it only says trust and the back of the coin is missing the word united is this an error
Thanks for the weight.
That seems to be 16% under weight.
(2.5g-2.1g= .4 .4/2.5=.16=16%)
I believe normal tolerance is 10% or .25 grams above or below normal weight (of 2.5 grams for a zinc cent).
All I'm saying is that it has the appearance of a grease filled die, but it also appears to be an under weight planchet also.
