I am fairly new to Autograph Collecting and will make mistakes but am glad to find this site. 
Can anyone tell me what Auctions to avoid since i have already noticed substantial differences in Descriptions, Autographs that look too new , that are too perfect, that have zero provenance , etc. I have followed LiveAuctioneers and stopped doing anything with them so I could legitimize these and other Auctions: 
RR Auctions 
The Written Word 
Heroes and Legends 
University ARchives 
Pieces of the Past 
NOrth American Auction Company 

thanks for any insight and advice on Legitimate vetted Auctions !
