A recent bulk submission included a rare San Francisco 1921 Morgan Dollar hidden among nearly 1,000 other Morgan Dollars.

An NGC grader was examining a bulk submission of nearly 1,000 Morgan Dollars when one coin stood out. The submission comprised a variety of dates and most of the coins were in low grades. These coins might sell for anywhere from $30 to $300 after NGC certification.

The sharp-eyed NGC grader saw one coin though that he instantly recognized to be an elusive Morgan variety worth upwards of $1,000. At first glance this coin appears to be a 1921 Morgan Dollar struck at Philadelphia with no mintmark. However, it is actually a San Francisco 1921 Morgan Dollar with a nearly invisible outline of the “S” mintmark – a result of the coining die being filled with grease at the location of the mintmark.

The grader knew that the key diagnostic for this scarce variety was a raised die gouge between the B and U of PLURIBUS on the obverse, which is prominently seen on this example. Morgan Dollar varieties are attributed as “VAMs,” an acronym created from the first letters of the last names of Leroy C. Van Allen and A. George Mallis, the authors of the first reference book for Morgan Dollar varieties. This coin is attributed as 1921-S VAM-6B and is listed as one of the “Hit List 40” VAMs.
