Advice on selling graded cards
A little background first. Relatively new to selling vintage cards. I had PSA grade a 70 Topps Pete Maravich (5) and 72 Topps Julius Erving (7) from my collection I've had since I was a kid. I was able to sell these on Ebay and did okay. Bought some warehouse cards online and got a PSA graded (8) 70 Topps Pete Maravich, and an (8.5) 72 Topps Julius Erving from my collection. I'm probably going to run up against the $1500 limit on Ebay as I do sell other things.
Is a business account on Ebay the way to go? Any downside to a business account?
What about consigning cards for auction? Good places, ones to avoid? What type of fees can I expect?
Open to all advice. Thanks in advance!
