Do post pictures! I agree you shouldn't drop test coins of any real value. There are plenty of other ways to detect counterfeits, plus a lot of of the fakes are made from real 1909 cents that they just add a mint mark, or even VDB, to. So any test to see if the coin itself is an authentic cent would come up positive in that case.
