I've never gotten a card graded, but I do own a few graded cards. About 15 of the 1971 Kellogg's baseball cards are probably good enough to be graded. I may have to ask someone for advice on this one.
Since my 1971 baseball cards are not in great condition, I got about 15 upgrades for my set and one new variation. That gives me 152 cards toward the master set.
I will be heading to the National Card Convention on Wednesday. Normally I don't find many cheap Kellogg's cards, but I'll be looking. Upcoming posts will probably mention what variations I need.
