1958-D Jefferson Double Mint Error Help!

Another clue that might indicate this is PMD:
In the last, larger pic, the straight side of your 8 and also the gashes on the front are all reflecting the light in the same way - all are bright. It would seem to point out that whatever hit the front of the nickel to make the long gashes also hit the side of the 8.

arcamonetravis,
Coins like this can be frustrating. When I first started, I thought everyone was too quick to assume damage instead of error. But as mentioned, a greater understanding of the minting process along with many experiences with circulated coins allows some of our more knowledgeable posters to come to a quick conclusion. I wouldn't consider myself one of those posters yet but I will say I've had many experiences with the post mint damaged "8's" that end up looking like a "B". Yours appears to be classic post mint damage. More importantly, there is really no way to conceive of a single coin being minted like yours in error.

The more interesting potential error is the rotated die. If it's 10 degrees, no big deal. If it's 190 degrees, it's a nice find. Take a closer look and see if the reverse is upside down. We don't know if you flipped it up and down or left and right. If you flipped it up/down, then you have a nice error.
