1982 Memorial Cents

That flipping of a coin to hear a difference in a ring is kind of a dumb suggestion since most coin collectors are on the elderly side. Not to mock the elderly since I'm well into being one, but such differences in sound is for the young, not us older people. Haven't you heard that there are some ring sounds that kids use on their cell phones that us older people can't hear? There are many, many sounds that older people just can't hear. No we are not going deaf, just getting old. I've heard that system explained so many times and it just is not for most collectors. And just who would flip a MS grade coin in the air anyway. Then there is always the smart people that say to just bang it on a table. You can really hear the difference then. GEE that would be a great way to test all coins such as a 09S VDB.
No my suggestion is to just melt them down with a torch. If Zinc inside they will melt faster.

just carl- well I meant that that system would only be for 1982's, which when pulled out of circulation for their (Possible) copper would not be BU.
