This is a decent example of the scarce 1901-O VAM60 Morgan dollar counterfeit associated with the Micro O family. This example exhibits above-average F/VF details for the variety, but the surfaces are a bit abraded.
 
There are seven (7) documented counterfeit Morgan dollar varieties dated 1901-O from this family. All are scarce, rare or very rare, and finding an example with better than VG details is tough.
