I saw on this PCGS lowbal set that they had a 1943 steel cent in AG3 condition. To my knowledge (correct me if I'm wrong), the 1943 steel cent was zinc coated in steel. Assuming that the copper plating on zincolns is of similar thickness to the steel plating on steelies, would it be safe to say that it is possible to wear a zincoln to AG3 without revealing the zinc core? Or, does the steel cent I'm referencing have an exposed zinc core? Edited by RoyCoinBoy 04/20/2018 6:22 pm

Just add some parking lot salt from winter and you get:

You sure that isn't an ancient Roman coin, Mark?

I would think not. Zinc does not hold up well to the air. A 1943 has a steel core plated with zinc. Steel holds up a little better. John1

This picture begs a question in my mind: How much does it cost the U.S. Citizen to make and distribute a Zincoln?
As I understand it, issued U.S. Currency is a liability on the U.S. Treasury, and that includes Zincolns.
The coin pictured would be un redeemable, and even if it was, it would still incur a cost of re manufacturing, so therefore best left un redeemed.
So THAT is how the U.S. Mint makes a profit on single use Zincolns!
Hence the question.

About the lowest grade I think a Zincoln can go is about EF before the plating is compromised. By good or almost good the coin is a slug like Mark pictured.

PCGS has a 2009-D (Formative Years) graded 10. If that's not a typo, I'd love to see a picture of it.

Comparing apples to oranges anyway. The zinc coating added no appreciable weight to the coin, was a very thin micron coating NOT a Multi-micron PLATING. As Mark stated, the stinkin zinkin is an essence a potential battery just waiting for a catalyst such as liquids, air to begin and electro-chemical reaction which in this case moves the zinc OUTWARDS through corrosion. When you put coins in an acid base, they turn warm...an electric discharge/transfer of subatomic particles.

To be honest, the AG3 1943 cent in that collection looks like PMD to me.

Spruett  , that circulation cameo loks done in Jonnie's workshop, it is too polished looking to be natural. After looking looking through those examples, maybe I outta send in my collections for certification, I have a few that would replace those they show!

Or, does the steel cent I'm referencing have an exposed zinc core? 1943 cents had a STEEL core plated with ZINC. Modern Lincolns have a ZINC core thinly plated with COPPER. Steel is hard and can hold up to circulation after the zinc gets worn off. Zinc is soft and rots easily. So it is very unlikely a Zincoln will ever wear down to the lower grades because the Zinc will rot first (as soon as the copper starts to get worn off).
