error nickel

The image is very faint but visible without a doubt. It jumped out at me tonight while going through a box of nickels. If you follow the curved image above the “p” in Pluribus, you can kind of see an outline of the obverse. What do you all make of it? Any help / opinion would be helpful.

Actually found this several days ago in change. I thought it was one of the new nickels but later thought more of what I had seen and was gonna look again. But I had to re find it. Turned up in a large cup and it is definitely not one of those new ones. Lookung for an opinion as I know nothing...
