1921-D Morgan - Missing letters

nesvt

Got this today. How can you tell what VAM this would be?

I see the 1AC has break at the 2nd L in DOLLAR. This coin does not.
The 9A has a die chip in Liberty's mouth. This doesn't.
11A has a break in the 2nd S of STATES. Not mine.

1AI? 1AP? 1AO?
Or is it just a filled die?

Probably just struck through grease.

Since the fill is centered around WE, I'd check VAM-11 anyway.
