danielscores

i recently purchased the #2 set on the psa registry and added a few cards to it. i still have a second set that is #6 and i don't know whether to break them up or sell the whole set. there are 144 cards and it seems like a lot of work. the set has a psa grade of 8.77 and is 100% complete. The set is listed and i have added some pictures of the first 20 cards. if anyone is interested i'm looking for $4,000. after shipping.
