I'm a product of the late 70's who collected older cards as a kid during the boom. I realize a lot of my cards are not worth much after the crash. The few worthy cards I own from the 50's, 60's and 70's, may be worth sending in for grading. I am interested in getting back into the game and adding to my collection. Do I need a silver or gold membership to access sold prices for psa graded cards or can I get that info for free? This looks site appears to be a great resource.
