Yep, most of the artists only did around 200 each, dan cooney did about 1000 and a lot of them are fairly average quality and are extremely similar, hence the reason they dont sell for too much, but if you pick up a sean pence, its worth at least $200+ katie cook is also fairly popular as well and the full color sketches are worth $$ due to the majority of the cards being just your standard black and white (or blue and black/white as it is with Heroes 2)
yeah exactly, that why select's sketches are so bad because everyone has the same sketch, where as in a high majority of the non-sport card sets, they are individual sketches all of different characters and all in different styles
