So I've had these sitting around on my desk for a couple months debating whether or not they are what I think they are. I finally decided to take pictures and post them here to get some opinions. If they are legit is there any value to them besides cool factor? Thanks for looking!
The 2nd one is almost a perfect outline of Lincoln's bust and the design is incuse to the coin. Looks like it could be an impression from a coin underneath it.
Sorry, meant to specify that the plating cracks referred to the 1983. As to the reverse of the 1970, I have seen that particular anomaly before but don't have a good explanation for it.
Ah gotcha. Whoops I should have specified that they are two separate coins on the the possible clashes. Not that it matters for the 2nd one I don't think.
