I picked up this coin which looked like a normal minor planchet clip error at first but if you look at the top left of the reverse picture which shows the edge surrounding the coin, the copper color and the nickel color are opposite than the rest of the edge. Like they somehow got flipped from the clip which doesn't make any sense. Any thoughts on what this is or how it could happen. Thanks

@Buddy. The picture just shows the reeding. It is not like that on the actual coin.

Nice clip! I'm not sure about the cladding layers though.

I see what I would tthinkis blakesly effect on the opposite side but nothing on the coin is missin really. Could it actually be called a clip or ? Also the revers cladding is only where it is Clipped/knicked so I'm sure that has something to do with it but I don't know what . Hopefully an expert explains this one . I would really like to know

That reversal of the cladding layers is exactly what you should see on a clad coin with a clip.

Twhen the blank is punched from the strip it results in "smearing" of the clad layers on the edge of the blank and the edge of the hole. This smearing will be in opposite directions. On the edge of the hole the top clad layer will be smeared downward and on the blank the bottom layer will be smeared upward. Now when the next blank is punched out overlapping the hole from the previous punch creating a clipped blank, the edge of the blank will be smear upward as on the previous one. But in the clip area the smearing will be downward as seen in the original hole.

The OP's coin looks like it had a very tiny edge clip. Large enough to cause the rim weakness, but so small that the planchet expanded enough to make contact with the reeded collar so the reeds show but weaker than normal.
