[Thrill-of-the-Hunt]

i have noticed lately alot of SGC "A" cards (assumed trimmed for the most part) are starting to sell for quite some money on ebay. there are multiple bidders as well.

my question is.... are authentic but trimmed cards collectible enough to spend $100 - $1000's on? or is this a great racket for card doctors whose cards get caught but still encapsulated? or, do some buyers think there is a chance to send the card back in for a numberical grade and make a nice profit? maybe all the above?

i saw a T205 cobb sell for $850 , a number of 1915 CJ in the $50 - $100 each, T206 HOFers $60 - $$$ as a small example.
