Can I submit a single card to PSA for grading purposes, or is there a minimum I need to meet in placing an order?

Yes, I think you can. However, the problem will be the cost. I think it's $18. If it were me, I'd wait until I had a bunch of cards, you get a whole lot better price.

Short answer is yes like Bam said.
Just depends on how quickly you want it back. I've got a sub I'm waiting on at the 10 day level that should pop in the next few days.

Honestly, I'd wait to get either 6 or 15 cards together, and join either the Gold or Platinum Club Membership. You get 6 grading certificates for Gold and 15 for Platinum. The Plat is what I do, get $270 worth of grading for $200, and a year sub to the SMR which is really helpful. Plus a cool coffee table book about some of the legendary bats in the game.
