PSA or Beckett are the way to go. If things haven't changed, PSA requires a membership. I think it's around $100, but you get 6 gradings with it, may be different now, not sure. Grading helps value certainly, it also gives buyers a better feeling about the cards not being altered or fake. Unless they are high dollar cards, it may not be worth the effort. Can you give specifics of the cards, maybe a scan or photo? Aaron cards from the 50s can vary greatly in value. Beckett is very tough on their vintage grading. I have a '58 Maris RC that would most likely be a PSA 7, that is a BVG 5.5 . Look at them with a critical eye for centering and corners. A popular thought usually with vintage, is that "it looks good for being XX years old". Graders don't really give the age any weight, they judge the condition as if it was new. Grading is mostly done by mail submission, some card shows will have graders; if they aren't PSA, SGA or Beckett, don't waste your money. If you can post a list of the cards with exact years, and a rough idea of what you think the condition is, I'd be happy to give you my thoughts on whether to grade them or not! Rob
