PRO Graded cards are usually authentic, but most of the high grade ones are trimmed.
I would love to buy low grade PRO cards because they will probably be cheaper than a raw card because of all the collectors scared of the PRO holder.
But Ive only bough PRO cards 2 times, and both were great deals.
One was a common Tango Egg card (McQuillen) I got for pennies on the $.
And the other PRO card I still have is this one below...
The slab is huge and very high quality, but its way too big for a card thats slightly larger than a Postcard.
I could use it as a cutting board!
