With over 100 million ms 1968 S nickels minted , from your images looks to be a circulated MS coin. In ms 63 value around 20 cents .
I think it's a business strike, and I disagree regarding full steps. Better photos might convince me. Got a shot of the obverse?
You're right, from the image not full steps. I just don't have any way to post better pics. Thanks for your help.
It's an impaired proof. You can see the mirroring in the fields right around Monticello in the first image as well as the very sharp and distinct steps. Also the rims are a dead giveaway as well.
