About other sales I dont know what to say, I just made a suggestion based on my sale, and the only sale that has happen in the last month, I have seen sellers at 22 (Arthur) and 20 (Me, Beff Jezos and Stonks Girl) but non of us was able to sale the unusual at that price, s/o of Arthur has been there for more than 2 months, I was only able to sell the unusual after I lower the price to 17 keys, and even then took a while to sell; I wouldnt say that 20 keys is a suggested price for the unusual, since it hasnt been sold at that price in a while, and still after my sale, and with s/o back at 20 keys those unusuals havent move yet, as a mather of fact one of them got put in marketplace, I'm not sure if 21 keys would be a correct price to be honest, there are 5 cardbeards at marketplace listed at 45 dollars, ~24 keys at current value of the key, and non of them as move all this time, in fact, last sale was in June of this year, I still believe the recnt sale should work perfect for a price suggestion on a non priced unusual, but its your call
