Here is an article on a 1974-S that was struck on a Phillipine 1 sentimo. The metal composition is aluminum. The coin weighs 0.5g. https://minterrornews.com/discoveries-5-18-20-unique-1974-s-aluminum-cent.html Here is another link with off-metal/wrong planchet price guide. https://minterrornews.com/priceguideoffmetal.html Maybe that will get you started in finding out what you have @Glenn Attalla .
Here's the problem - the mint didn't strike coins for foreign governments in Denver in the 1970s... https://libertycoinservice.com/wp-c...s-checklist-foreign-coins-by-us-mint-type.pdf
That sure is a good looking coin you have on this thread. This one looks like it may have a chance of being struck on a foreign planchet because it is under weight for a copper cent. You may want to send it to a error coin expert for a in hand exam.
Really I’m not gonna take the time just to weigh random coins so you can believe that my scale is accurate. You just have to take my word for it since I know what I’m doing and I wouldn’t waste my time posting if I had broken scales.
I can’t find a decent coin expert to save my life I got a nickel Louise 4.15 g and it is the exact same size as a regular nickel for that year. I tested it with a EXRF or something like that and it’s not silver however the patina and everything makes it appear to be some thing else. Btw....error coins like these are what I collect.
When it comes to nickels don't pay much attention to the color because they can become every color in the rainbow. I think ANACS or NGC would be good places to send the cent to. They should easily be able to identify the metal content .
This link to the mint error news has large spreadsheet of foreign coins struck by the U.S. Mint. It's a little cumbersome to work with, but you can search for something struck in Denver during that timeframe and matches the weight. Happy searching https://minterrornews.com/news-5-13-03-foreigners_in_the_mint.html
Could be a few reasons why it's only 2.8 grams instead of 3.1 or 3.2, but in any case, without a doubt, your photo is of a plated 1975-D Cent.
I said that and he blasted me. Lol Even Fred posted above your last post and said it's plated, which all more experienced collectors have said.
I see you got a new balance. Any word on this one? I might have missed it. https://www.cointalk.com/threads/2000-d-nickel-4-15g-gold-tone.348492/page-3
Sorry but you are wrong here. All more experienced collectors have not said the cent was plated and that includes me. I have been collecting all different types of coins about as long as about anyone alive , That includes Mr. Weinberg . I remember buying coins from him way back before we even had the internet. Like I have said earlier . I doubt if anyone on earth can look at a photo of a coin and can say for certain it is a plated coin unless the plating is flaking or coming off.Also in the OP'S post #19 he said he said if the coin was plated he could not scrape the plating off . Sometimes it is good to read the info. that a OP gives.
The OP thinks his coin is valuable. Why would they try to scrape the coin if it was? Sometimes it is good to think about that. That coin is plated!
Serious question: how can you guys tell the coin is played just looking at the picture? Or is it a fair assumption given that there are no documented cases of off-metal strikes?
