leonI believe Superior was owned by, or a part of CU/PSA. I always thought it was a major conflict of interest for a grading company to be selling their own cards? I got the highest graded N284 (Buchner Gold Coin) in existence from one of their auctions. Ironically it was in an SGC holder 
......I have since had it put into a newer SGC holder....BTW, I am told there will be a set of cards for sale in the Mastro Live auction that is absolutely unbelievable. Almost monumental.....I won't tell what though as it's not my place to...I think there will be enough exposure that any lots in the Mastro Live Auction will do fine......best regards
