55 topps is a great set. I just completed mine about 2 months ago. Most of mine are raw but when it came to the high dollar hofs i tride to get graded ones when possible just because there are some fakes out there. The best place i found to buy where at card shows. Most dealers will discount for large lot purchases and you can pick out the cards in the condition you want. I bought a few lots off ebay but ended up only keeping a few because of condition. good luck with yours
heres mine
