I checked a list of all foreign coins minted in the U.S. The one that caught my interest was a 1943 25 cents-tukken. The composition is debatable as I researched the coin further. The records from the list I read claimed the 25 cent-tukken was struck on a planchet of 87.5% nickel and 12.5% copper. The coin weighed 4.5 grams. Thats the only possible foreign planchet theory for my 4.4 gram quarter. Will attempt to upload pictures now. I only have my phone at the moment. I've ordered a microscope with usb connection that should be here in a few days. By the way. There are black looking pits but not like you would see in toning and Washingtons face looks like his bottom jaw is gone. I have familiarized myself with amateur grading over the past five years and whats odd to me is the fine detail of the feathers on reverse and hair on the front. Diameter is correct reeding is also correct. Give me a few minutes for the pictures.

 

I have pictures. I tried to upload them twice. They may show up or may not. It's been suggested O start my own thread. Please check it out as I learn to navigate this website and the files in my phone.

 

Alright. There's a pic of the front, back, and edge. I could show you the digital weight but whats the use? I could fake that. Please believe me the coin weighs 4.4 grams. I am also ordering more accurate scales as mine only measure to the tenth of a gram it could be a few hundredths give or take. As the pictures are here should I still start my own strand? Is it even possible a coin minted in 1942 could be struck on a planchet intended for 1943?

 

I've heard of thin rolled coins but if that were the case wouldn't at least 100,000 or so have been minted and discovered by now? I'm far from an expert, more of an enthusiast. I plan on setting up my microscope to look for varieties and errors while i day trade. Heritage Auctions ask I send them pictures of my best 20 coins. I dont know where to begin.

 

I believe that coin is just the victim of extreme environmental damage. Acidic environment, chemical or something.

 

A die struck coin would not have that mushy, washed out appearance over both sides regardless of composition. Research images of coins struck in thin/lightweight planchets.

It looks like the coin spent some time in an acidic environment.

 

Unfortunately that quarter is just a regular coin reduced by something acidic. Just worth the scrap value of the remaining silver.

 

That would account for the discrepancy in weight & width? I agree I've seen many many coins turn that same shade of decayed black. It's obviously not toning. I've found one other coin that reminds me of it. A 1964 nickel I believe. I will pull it out and post pictures. All the image is there but similarly squishy numbers and letters on the entire coin. If memory serves it still weighed 5 grams.

 

It would definitely account for the weight and width reduction. It's really the only explanation that would.

 

While I was looking for this coins, takin into consideration your input, it occured to me this could be a combination of factors. This nickel with the letters and numbers squishy, seems like it was stuck in a counting machine. The quarter looks like it came from under my car seat after marinating in some of my daughters spilled coke. If it was a rolled thin quarter, that spent time in an acidic environment, then got stuck in a coin counter, that could explain it.

 

If this quarter with clear details under the crud has more time the image will dissolve? The rim was the first thing to go? How about this cent. Do they let stuff like that out purposely or could someone do that with a blank?

 

Your cent is a legitimate off center error. The quarter just appears to be covered with crud or corroded. I am not sure I understand your question, but the quarter won't just dissolve from crud. Acids or burial in the ground can cause corrosion and damage.

 

You didn't say what country that 25 centstukken was from, but I checked the list and the US never made a 25 centstukken for any country with that composition. They did make a 1943 5 centstukken for Curaco with that composition and a 4.5 gram weight, but it was also only 18 mm in diameter, about the diameter of a dime. Your quarter doesn't look like it is struck on a planchet the diameter of a dime. so that possibility is out as well.
