Not a struck through because a struck though would be incused. This is a beauty! It's gotta be worth a few bucks. Nice find!
Definitely not a struck-through. Appears to be a cracked obverse die. I suspect the die fell apart not many strikes after this coin was struck.
Don't know how you're gonna add metal to create something with a raised relief like that and have it come out so clean.
Raised? Am I missing something? I don't see a raised area and yes you can add metal to create something with a raised area.
This may be WAY off, but I cut a gash on a nickel with a hockey skate (looks identical, but two sides?) Anyway, keep it.
Two entirely different things. The gash you cut into your nickel is below the surface of the coin, right? The metal on the OP's dime is raised.
This is most definitely the coolest cracked roosevelt dime I have ever seen. They are pretty rare, I guess because the die is so small? But for the right collector this would be big $$.
You are absolutely right Mike. Now I see it better and I also see the raised area/cracks. It is with no doubt an error. Looks almost as if it almost created a lamination of some sort. However, I do agree it is a die crack, a "spiked" die crack variety and on a dime is pretty unique specially that large. It is a spiked variety because it is straight, running from the edge of the coin and onto the portrait X2. Very nice coin. I would send it to get certified by NGC although it wouldn't get a high grade, it is a unique piece and well worth encapsulating. Thanks for sharing. Edit: Besides, the spiked die cracks, I do notice that the coin was also/possibly struck on a grease filled die because of the unique wear on the portrait (hair and ear). The rest of the coin looks as common wear, this is where I get the "filled die" assumption from.
