PSA cards. Do you have a grading range that you typically look for?

[the 'stache]

If there's one thing I've learned since joining this forum, it's to buy the card, and not the grade. That's a wonderful piece of advice that I now employ whenever I look at vintage auctions on Ebay.

But I would ask you guys that do buy graded cards (even if you do so only to free them from their plastic prisons): Is there a grade that you typically look for when buying? Do you start by looking at PSA 6's, and go from there, evaluating each card on sale. Or, do you look at 5's, and see if any of them, in your initial examination at least, might be of better quality?

I'm trying to find a happy medium between buying very fine quality vintage cards without breaking the bank. I'm not looking to ever sell these cards, but I do want to make sure that the cards I buy will maintain a strong resale value just in case the need to sell them were to ever arise.

I understand, too, that the grade range depends on the cards I look at. A 1952 Topps PSA 7 high number card will be expensive as hell, whereas a PSA 7 from the 1973 Topps set will be quite affordable.

I guess I'm just looking for some input from you veterans. I'm the nervous rookie, currently laboring away in AAA, getting ready to be called up to the Big Leagues, and I'd like to know what I should be looking for. Like the game of baseball itself, there are subtle nuances that newbies like me should learn. This is my dipping my toe in the pool before I jump in cannonball-style.

I don't know if that makes any sense. I hope it does!

Thank you!!
