They are no F U C K I N G good. The top notch items go to " Friends" . Auction my ASS.
I personally know a high end dealer with many great items , many with historical value with provenance 1.75 Mil . his cost, received less the 700K after being wooed by RIA.
Another gun shop owner with fabulous lifetime of collecting , sent his items to RIA for his retirement after selling his shop. Same thing less than 1/2 appraised value.
I know these guys personally.
I do not like auctions, especially this one.
