It's all good. My collection is all over the place. The majority of my cards are graded, but I've bought most of my cards raw and submitted them. about 20 percent of my collection is raw. I'm almost at 100 t206s
. For the rare backs, I usually stick with lower grades because I can afford them. Commons on the other hand are good because you can get a nice looking PSA 5/SGC60 for about $90-$110, depending on the player, eye appeal, and how sharp the corners are of course.
