Regarding N#1493, the two entries for "2020 W" commented as "burnished" and "uncirculated" should be merged - perhaps to “burnished = uncirculated”. The US Mint sold only one West Point mint mark silver eagles in 2020 with a non-proof strike. While the US Mint seems to refer to the strike as “uncirculated”, the major grading companies have used the “burnished” nomenclature used by the mint in the past.

Here is the US Mint product page for the "uncirculated" coin from Dec 30, 2020:

The grading companies NGC and PCGS refer to the same coin as “burnished” and have no entry for “uncirculated” in their catalogues:
