1983 Certified Bronze Penny

He found it by weighing and sorting through $40-$50 in pennies every day for several years. It's pretty much his 2nd full time job. He has found many error coins but he's been looking for this one and I was happy to tell him he found a winner :)

I don't see where an 83 copper is any more implausible than a 43 copper, 44 steel, or 46 warnix. When you're making tens of billions, stuff happens.

Just that an 83 copper isn't as obvious.

Great find, love it! I bag all 1983s and when I have several dollars saved up, I then look for the different varieties at one time but I always weigh them before putting them in a bag.

I am sure you are going to share the proceeds with your Ex, no doubt? ;)

Any proceeds from the coin would naturally go to him. He's the one working for it! I'm not "one of those" kinds of an ex haha He's doing it all for his kids anyway. I just try to help when I can.

WOW!

I missed this thread - I know it's old but....




Are you selling this coin?

Uh...nice find :-)

Bronze is an alloy of copper, tin and zinc. For US cents it was 95% Cu, 2.5% Zn and 2.5% Sn.
Brass is Copper and zinc in the US cent 95% Cu and 5% Zn.
Most in the hobby incorrectly refer to brass as bronze and thus you have what might be a brass coin being called bronze.
The latest 1983 Copper Alloy cent was found and reported last week to be an alloy of 93.35% copper and the balance zinc, iron, nickel and a very sight trace of silver. So with your coin being underweight by a significant amount I guess I'd want to know what the exact composition is before I'd buy it. It's troubling that it does not say Transitional or Pre-1983 1c planchet on the slab anywhere. A 1983-D certified by NGC as 98% Copper and 2% zinc was referred to by them as brass. It weighed in at 3.0 grams. When I asked David Camire, NGC's error attributor, if he considered it a transitional he said he didn't suggesting is was a planchet of unknown origin ... so you have to be careful when all the information about a coin is not known such as the exact alloy. I suggest getting it slabbed again and having a more detailed analysis of what the exact alloy is.
