Then your coin was hit twice instead of just once. Opinion as to how a Mint process could create this anomaly would be welcome, as those who have been looking at them for decades can't come up with one.
The easiest way to answer the question, "Is this an error?" is to figure out whether or not the Mint could have created it. The missing metal would have to correspond to something *extra* on a die which wouldn't normally be there, and the *extra* metal on Monticello would have to have been material removed from the die. Since that area is a negative on the die, something would have to accurately reach "into the hole" and gouge metal from the hardest steel it's possible to create - steel strong enough to strike nickel, which is as hard as steel....
That's the key to identifying errors - knowing Mint processes. Once you learn that well enough - and it's common to all dies and all issues, so you only have to learn it once - you can figure out what you see on just about any coin.
