1941 Wheat Penny Possibly On A Foreign Planchette?

Yes I did which is why I'm Seeking opinion

the Panama 1¼ centesimos (KM# 15, Panama "SCWC" number for the planchet) is 20mm diameter and 1.15 thickness.
the Lincoln Cent is 19.1mm diameter and 1.52mm thickness. (KM# 132, US "SCWC" number for the planchet)
Both weigh 3.1g.

Now, the Panama 1¼ centesimos was actually struck on Lincoln Cent planchets, absolutely no difference as far as the planchet goes before the strike, the same stock was used for both coins, 3.1g weight, the difference between the two lies in the diameter and thickness due to the collar used.

Now the 1941 wrong planchet example that exists and graded by PCGS was stamped on a 2 1/2 centesimos (KM# 16 Panama) which is a different composition and weight. It was copper nickel.
The 2 1/2 centesimos had 3.3 grams and a diameter of 18 mm, and it was slabbed with incorrect info on the label, it's not a panama 1C planchet

there would be no difference between a Lincoln Cent KM# 132 on a KM# 15 planchet, because its the correct planchet for the Lincoln Wheat cent and used by the US mint for both coins when they stuck both of them.

The error coin is on a KM#16 planchet. If you look at "1941 Lincoln Cent Struck on a Panama 1C Planchet -- MS65 PCGS" you will see pictures of the slab. it was labelled wrongly as "stk on Panama 1C plan",
This coin is the copper nickel Panama 2-1/2 Centesimos KM# 16 planchet, clearly evidenced by it's color.

I've gone down this rabbit hole myself and done the research to come to this conclusion already, feel free to look into it yourself independently.
What you have is an underweight Lincoln Wheat cent. Probably at the low end of the tolerance, and then wear I think, for sure it's not a wrong planchet or an off metal.
I also don't have one of them 1941 off metal Lincoln Cent on panama planchets.

Very informative with out making me feel like I asked a stupid question. Lol Thank you for taking your time to give me a detailed explanation. if only everyone could reply with an educational response instead of a know it all answer.

Sorry if you thought that was directed towards you But it totally wasn't. And I didn't mean it towards anyone specifically it's just sometimes people give you a short condescending reply and I was appreciative of him taking his time to give me a detailed Explanation that's all that was.

to CCF...good question/inquiry..great replies..

Only reason I know what I do on this particular specific subject is I thought I had one for a time too and researched like a mad man on it.

There is no one complete, accurate list of every coin the u.s. mint produced for other countries. I think it's somewhere between 1200-1500 coin types and dates over 100 years.

There's a book called "Foreign Coins Struck at United States Mints" by Charles G Altz and E. H. Barton, this covers most of 1876-1963.

Then the ANA library has a copy of a report issued by the Department of the Treasury, Bureau of the Mint entitled "Domestic and Foreign Coins Manufactured by Mints of the United States, 1793 - 1980". Again not complete and stops at 1980 and it's all listed by fiscal year, which doesn't always line up with the date on the coins.

So then kind of have to cross reference with "Standard Catalog of World Coins" for KM#'s to figure out the dates and what happened.

In fiscal year 1940 the u.s. mint struck about 1.6 million 1-1/4 centesimos as well as a couple million 2-1/2 centesimos for Panama. These would have been dated 1941 though due to the actual year at the time of minting.

I don't know much of anything else though lol. I just did my homework on this subject because I though I might be rich with a 1941 on a panama 1 cent planchet.

Khrys welcome to CCF...great question with a fantastic response meant to educate. Everyone learns.
