Rarity Rankings: I thought I had posted this before, but I guess not. Anyway, it now covers 3 decades and nearly 80 years.
Below you can see the Top 15 coins from Ultra-Rare to Semi-Rare based on various rankings. The 1940's/1950's was before the wave of hoards hit from Europe and South/Central America and based on dealers guestimates. The 2000's was based on the Akers/Ambio Gold book rankings. The 2020's rankings are based on Roger's book.
I mentioned before how the 1921 had moved less over the decades than other coins, you can see that below. It moves from 4th to 3rd to 6th. Other coins move up or down alot more.
