I am new to the card grading community. I have a bunch of hockey cards I am trying to sell, one of which is a Wayne Gretzky O-Pee-Chee rookie. I tried listing it as an ungraded card on ebay and I was denied for reasons that the card is easily counterfeited. I was then explained that grading it would solve my problems. I have graded comics before, but not sports cards. I have found a number of places that grade, but I was curious to know what my card would be graded at BEFORE I send it off (trying to figure the cost-benefit analysis). That would help me figure out where I should send it for grading.

Any help would be appreciated. Thanks.
