The mint melted all of the sheets that they punched blanks out of so that they could reuse them. Never did they save any of the punched sheets. If you are trying to say that you know it's a mint-punched strip because a cent fits perfectly inside of it, it isn't a mint-punched strip, as the blanks they punched were a lot bigger than the final coin.

Interesting point! Yeah...the rim upsetting mill would reduce the planchet size, wouldn't it?  |

I think the final size of the US penny is determined by the size of the collar of the coining press. I would guess the planchet spreads slightly to fit the dimension of collar, but the raised edge created by the upsetting process does relate to the size of the rim of the final coin?  Perhaps one of our experts can tell me for sure and provide some precise measurements for planchet size before and after the upsetting process? |

Back to the topic though, just what is that thing then? If not for coins, possibly just a sheet of steel to sell to people as a possible sheet for coins? Or just a sheet of steel for making washers? Also, is this sheet coated with Zinc? Lots of questions.

I am pretty sure that the zinc process was done after the cutting or punching was done. or the edges would have the steel and not zinc coat on it. other than that I am going to have to agree with gb on the size thing. I have a few that are rimmed and some not "just punched out" but will have to find them again

the us mint never punch out the steel pennies.this was done as a off contract.these penny punch would had damage the mint tools not made for steel punching it take twice the force to do this.copper, silver, nickel and gold are soft metals.steel is a hard metal

I do not know for certain if the 1943 planchets were outsourced, but the current planchets are outsourced from Jarden Zinc; so outsourcing at the mint is not unheard of. IMHO, it makes sense to me that they received zinc coated steel planchets from a contractor, and not the usual rolls of metal to stamp the blanks.

If the sheet is not zinc-plated, then it was not used for 1943 cents. The sheets were plated with zinc and then the blanks were punched out, leaving steel exposed on the edge of the coin causing many of them to prematurely rust.

I have no doubt that it is steel cent webbing. Believe itor not that stuff is fairly common. I have seen a lot of it over the years.
