Merc collectors take note: 1937 PR-66 CAM not listed in pop report

RGL

Heritage has a recently graded PCGS proof Merc up for auction that does not show up in the population report. Lousy photo makes it hard to detect as a cam, but here it is:

PCGS 1937 PR-66 CAM Winged Liberty Dime

Placid

Cert number say's its a 66cam in the database.
