Good luck.
The amount of fake PSA slabs is tiny, most are know as the craigslist cards, they were all expensive well know cards like 33 Goudey Ruth, etc, if they show up on ebay they get flagged and pulled within a day usually so little chance of getting one there. If someone in person offers you a great deal on some of the hobby great cards at a steal price, run away as fast as possible, if it looks to good to be true, it probably is. There are some made to look like PSA flips but if you compare them vs a real slabs you can usually tell based on text and the UPC code are easy give aways, still not a lot of these out there to fear buying a graded card.
Best thing to do is before you purchase an expensive card, post it on here and let the experts verify its a good card if you are worried. If you dont want to "out" an auction going on, then have a person or two you can send a link to and they can look at it. Plenty of experts here who can help.
