Found this in pocket change. Was kinda surprised it had so many bumps on it. The mint sure is getting full use of the dies when they let them go this far. I have seen a few of these bump on recent year dime, but not one with this many on the front and back. obverse = 10 bumps and 1 fine crack, Reverse =7 bumps and 2 fine crack. sorry photos are not to great, it is hard to get lighting right to make bumps show.
I find more dimes with these type of anomalies than any other denomination. I think it is because of the small diameter dies and planchets. Not enough die metal to absorb the constant pounding of making coins. With the dime, the design leaves very little field. The reverse of the dime almost does away with the field. That leaves very little flat area on the face of the dime. There really shouldn't be any reason why the mint would have to use a die right up to total failure or beyond its useful life. Not like they are hand making dies these days. Dies should be relatively cheap to make and plentiful. Cool find. I would keep it.
