Ok folks, I read all explanations and I agree with the photos of COOP's for the #2 of the quote of causes for missing clad.
Now, this coin is impossible to happened at the mint facility and I can tell you is not my first FAKE see to try to do an missing clad.
NOW:
#! Yellows line= rim deteriorated
#2 Red Circles: very strange marks on the rims. Seem someone want to take out the clad
#3 Green circle= unidentified way to produce those marks.
#4 Yellow circle= rests of the clad on surface
#5 High part of the Observe= have not an strait line of missing clad which it is characteristic of all mint missing clad errors.
#6 Surface of the coin= show acids action on Cu and Ni
#7 Reverse= very clear acid denaturation
Extra: I suppose that the side of the coin show Ni.
This it is my opinion for this coin and it is not the first see like this.
PS: If was Mint problem of the point 1 of missing clad we can see marks of chemicals (those are alkaline and not acidic)

#1 - Chemical impurities in the bonding process
Clad coins are created from bonding different metals together to form multi-layered metallic sandwiches.
When impurities get in the way during the bonding process, these impurities can cause the nickel clad layers to split off from the copper core — exposing the copper inside the sandwich. The clad layer may come off the entire coin, or it might flake off in segments. This can occur before, during, or after striking of the coin.
#2 - Manufacturing errors
Another way these missing clad errors are created involves a different type of manufacturing error.
Sometimes, error coins that are missing their outer layer of nickel clad happen when the outer strip of metal isn't wide enough to overlap the copper core layer — which results in only part of the coin being cladded with its outer layer.
