Their ebay listing name was/is collectnuts!. I would occasionaly see items listed by them and once or twice I did win items that I was very confident of the authenticity - Olympians. However, some of their items make me uncomfortable. Perhaps Mark or Travis will offer an opinion on the Leo Hauck or Sugar Ray Robinson signatures. Unfortunately their images are way too small to get a feel on many of the items and just from a collecting standpoint some of them seem terribly underpriced for legit items such as a Bob Dylan signed poster for about $120. I would think 2-3 times that if not more. Their website
www.collectnuts.com.
Disclosure - I worked in Worcester 1990-2004 and lived there 1999-2004, but never heard of them.
Cheers,
