I took these pictures looking into the edge of the 1829 Go MJ coin in eight places.
My intent was to see if I had a seam, but I'm not sure if there is or not.
I know the substance results from copper corrosion, but I mention it here because no such similar images can be found on the other 5 coins.
How meaningful may this be regarding how the coin was made, if it is at all?
