1880-O Morgan Silver Dollar PCGS MS62 (OH) – Micro O Variety Better Date – VAM?

Better Date 1880-O Morgan Silver Dollar , Micro-O Variety Graded PCGS MS62 and housed in an older non-edge view blue holder. I do not have the patience to check for VAMs so I leave that to the next custodian. Obviously it is some VAM with the Micro-O mint mark, but whether it is common or not, I have not researched.
