3 different marks of this type are seen AoA, oAo and AAA

I'm certain it has to do with the Gold content.

Gold filled, Gold plate and.... ? 

I want to say base metal, solid Gold is usually stamped that way: 14K, 18K etc.

I could be wrong

I don't think anyone has ever figured it out.

Gold quality is correct. I think Alex was able to provide a definition of the 3 variations in quality. Trying to find that information.
