1941D Lincoln wheat penny it weights 3.31 grams (verified 2)sets of scales). I think by the looks of it . It could be brass I think it could be on a wrong plachet or struck over ....do we know if there were any Peruvian plachets being struck in D in 1941...... Missing the L in liberty
Just a slightly rolled thick planchet. The weight spec for cents is 2.98-3.24 gms, so it's only 0.07 gms over. Not enough to have any extra value.
