I think there are a lot of cards still ungraded. But, anyone trying to guess percentages is silly. I have some raw cards, but almost all of mine are graded. I think the card companies do a great job, and I don't have to question the authenticity or damaging them. I have mostly caramels, and they're prone to chipping. So, enjoying them in a solid holder is my personal preference. Also, I think it would be unwise to buy or sell any cards that have significant value ungraded, unless you really know the provenance of the card.
