50,000 are from this set (the other 75,000 were from the Congratulations Set). This kind of number represents a fraction of the normal proof Silver Eagle mintage - most proof Silver Eagle Mintages are from 400,000 to 1.4 million. If you look at the mintages of Proof Silver Eagles over the years, 125,000 represents the third lowest mintage ever and the second lowest mintage of regular proof strikes.
Of course, I'm just talking about 1 coin. This set has eight total silver coins, in a nice US Mint case and of course, it has the much sought-after 2017-S Silver Proof American Eagle.
