I thought I found a nice stash of 1982 pennies, but now I am questioning the finish on the obverse. Seems un-naturally glossy compared to reverse. Possible someone coated the front with clear coat? Ever heard or seen that. I assume if that's the case they ruined a decent collection. And again I assume I would be doing worse by chemically removing the clear coat (if it is clear coated)? Opinions and observations? Thanks!   |

It's hard for me to tell by the pics if it's coated or not.Could just be toned. John1  |

Looks like a normal 82 with maybe a little better luster.

Update: no clear coat... Not sure what it was. Became sticky with heat from my finger. Dipped in hot water, patted dry and looks normal now :) maybe something was spilled on them at some point. Appears to be a nice set. Have some large dates and small dates... Now just have to figure out how to tell which ones are bronze vs copper vs zinc... Any helpful tips on that task?

If you have a scale, weigh them, zinc = 2.5 grams copper = 3.1 grams

they are either bronze or copper plated zinc,so the weight I gave you is for bronze not copper

Just looked it up,sorry for the misinformation,they are .950 copper and .050 zinc.they are copper not bronze. wheat pennies were bronze because a trace amount of tin was added.the weights that I gave you will still work to find the copper vs zinc

If you have a good ear, you can make it ring by dropping it on a table or flicking it up into the air. Coppers ring a lot, and zinc kind of just goes clink.

Yes and you could also melt it with a torch, melt it with acid, cut it in half with a saw. Never could figure out why people say dropping coins to hear them ring. Obviously not a coin collector. |

I ended up buying a scale. Figured I will need it in the future anyway. Plus I had a ton of 82's to sort through. Made my job super fast and easy :) 14.99 for a small digital scale seemed like a solid investment for my new hobby :)

If it's just a run-of-the-mill 1982 cent a drop on a table isn't going to harm anything. Of course if its a beautiful BU specimen I'd definitely stay away from that, but it can be a quick way to sort through a bunch of common circulated ones. |
