FWIW, believe there is a 20% buyer's premium at S&B, so buyers were ultimately willing to pay ~$88,500+20%. No commissions here, so might be able to get a bit more than .06
BTC premium...call it ~.2-.25
BTC for the right coins. Higher premiums however, have been hard to fetch as others have noted. Could change based on market sentiment at any time though...market dynamics have created unusual results in the past for the right collectibles.
