2021 W Proof Silver Eagle PCGS PR70 DCAM Advanced Release.
Only a small fraction of the entire mintage is eligible for this exclusive designation. This is a new U.S. Mint program and they haven't decided if they're going to do it again.
They were released a week before the actual release date of the 2021 proof silver eagles. This means they're the very first to be released, period.
These are the top-tier coins with an exclusive pedigree that has never been seen before. They are the absolute best of the best coins you can find, with the PR70 Deep Cameo grade of PCGS.
