I cannot find anything on the internet; was there a special minting in 1964 of U.S.A. coins that were larger than normal? I got these three which in the holders look like normal coins ...
My three are not magnetic, have the correct edge, and 25c is 1964D but no mintmarks on 5c and 50c. Only difference I can see is their size (about 13% bigger) - 24mm / 27mm / 35mm
Does anyone know of these ? Luckily I also already have 'normal' coins to compare with ...
Maybe as that 1/4 dollar was the last time it was made in silver in 1964 there was a special set made. Also that Kennedy 1/2 dollar was only made in 1964 i.e. same year. I do not have a 'larger' 10 cents, but maybe there was one of those (and a 1 cent) as well?
The only other larger than-normal coin I have is a UK 1847 Gothic Crown ... https://en.numista.com/forum/topic10984.html
To clarify what I think ZacUK meant, the Kennedy 1/2 dollar was made in 90% SILVER in 1964 (for circulation; the mint still makes 90% silver proofs). Kennedy halves were made of 40% silver until 1970, and continued from 1971 until today in copper-nickel.
As far as the over-sized coins, I don't think they are mint issued. I've never heard of anything of that type.
I DO find from time to time see very large US "coins" that were made and sold as paper weights or ash trays, but these are over 3 inches around (much bigger than the ones you have pictured).
More likely novelty coins. I have seen novelties or replicas made that are much smaller, they call them miniature replicas and can be found on Ebay U.S. all the time. Making replicas of U.S. currency in the actual size is considered counterfeiting so they must be made at least 25% smaller or larger.
The minature coins are made simply to trick unwary bidders who don't always read the entire fluffery of the ads which use extremely deceptive terms to conceal the fact that they are worthless. This is especially true of the "gold" replica coins which conceal the fact that there is no actual gold content by such terms as "HGE".
At the other end of the scale there are the oversized coins, typically 3 inches accross and used as drink coasters.
The coins shown here don't really fit into either category, someone has put a lot of effort into making a set of well engraved coins. I really can't see the purpose behind them. I've never seen anything like these before.
Perhaps it's the result of a school engineering project?
Non illegitimis carborundum est. Excellent advice for all coins.

The toning makes them look silver, I must assume that they were made to sell as the real thing over the internet, when you see the photo it all looks right.
Did you buy these online? If so you should see if you can get your money back.
Taking a break from swapping for a while, but still interested in pre 1799 Spanish coins, I will make time for that!

Engineering project? Hmm, now I'm really curious to know what their actual weight is... Just Imagine if they weighed the exact same as the normal sized coins.... Could someone have possibly taken actual coins and enlarged them somehow ?? Hmm...
