OSV is a verification service. We do not grade coins, buy coins, or sell coins. As an independent verification service, dealers and collectors alike, are assured that all sets stickered by OSV are indeed authentic and original.
OSV will accept Double Mint Sets for grading, prepare those sets and deliver them to ANACS for certification. Once returned from ANACS, OSV will affix tamper proof hologram stickers to all boards that are truly original. On all boards that contain coins with exceptional color for the date, OSV will affix Color Premium hologram stickers. The sets are then returned to the collector or dealer who submitted them.
As mentioned, OSV does not grade the sets. ANACS does not verify sets, but grades each coin individually. The proprietary formula used by ANACS for the cumulative grade for each board was developed by an OSV consultant.
