GSA Question. What would be the answer as to how this happened?

This GSA was sent to me for imaging. I understand the reverse being bag toned but what you think would cause the front to tone like that as well?

Gorgeous coin. By the crescent toning on the obverse, that looks to be the bag toned side, with another coin blocking the lower section from the bag surface. The reverse to me is the question mark.

Bag toning in both cases.....these bags were moved in the valuts sometimes which caused coins to shift....the reverse was again the bag ther longest and then if the bag was moved it could have shifted to where the obverse of the coin was close to the bag with one coin partially blocking...hence the crescent. Sometimes coins were close to seems and both sides might actually be touching the cloth but in this example I think my first theory was correct.

That makes sense.

I agree with Shane as to the probable cause.
I'm more interested in the untoned slice on the reverse.
Who cares to offer a guess as to how that happened?

Any guess would be pure speculation as to why this area did not tone like the rest of the reverse, but to me it appears to resemble a lamination flaw, not a complete separation type flaw, but perhaps an incomplete metal fusion that was eventually rolled out into the strip. It could be something as simple as an impervious lubrication smear, who knows.
