Looking or help with this odd size Mercury Dime

Has anyone ever seen something like this? Can anyone offer an explanation as to why the one Merc is so much larger than a normal dime??

That’s weird. I vaguely remember reading about someone who wrapped a coin in leather and hitting it with a mallet and making it larger without flattening the details off of the coin, so maybe something like that happened?
Mr_Spud
If you put a coin between 2 pieces of leather and pound it with a hammer,the coin will expand without noticeable distortion. You can find novelty cents called Texas Cents that are made like this.
Looks like it could be a novelty item.
I agree with the above explanations. That method has been discussed several times here before. Cheers, RickO
Maybe Liberty is retaining water? Peace Roy

They call 'em 'Texas Dimes' or whatever the denom is.
Put between a piece of leather, and squeezed.
