100% pure/raw for me
If you care about reselling and the value then I understand slabbed.
Short story/memory: Back in the 80's I was at a card show with my Dad and there were some coins there and they were graded. I asked Dad did he ever think they would do that do baseball cards and he said
"No way. Look at that coin, what is the first thing you see?" I said "the number." He said,
"Exactly, that is why they will never do that to cards as it would take away their value."
He passed 20 years ago and I don't think ever saw a slabbed card.
Ironic that it increases the value not decreases as he predicted.
