Any of the high end memorabilia delivery systems produced in the past ten years immeadatly come to mind.
Realistically, I can't afford to complete the early NBA sets...the earliest I can hope to complete is 1971-72, which I have done. The 48-49 Bowman set, the first set, has some major stoppers...even the most common base cards start around $20. 57-58 Topps has Bill Russell's rooke card and Bob Cousy, Bob Petit, and more. 61-62 Fleer has Wilt Chamberlain's. 69-70 Topps has Kareem Abdul-Jabbar's rookie card. 70-71 has the Pistol Pete Maravich rookie. I don't expect to finish 72-73 Topps due to Julius Erving's rookie.
Moving to the 80s, the 80-81 Topps set has both Magic Johnson and Larry Bird rookie cards. None of the three Star sets are realistic, with the 84-85 set having the rookie cards of Jordan, Olajuwon, Barkley and more. 86-87 Fleer has the Michael Jordan 3rd year card that most people incorrectly refer to as his RC, which I cannot afford.
The only true stopper of the 1990s is 1996-97 Topps Chrome Kobe Bryant. The Dirk and Vince Carter SP Authentic rookies are likely never going to be in my price range either. However, I put much more emphasis on pre-lockout cards.
Even the sets I know I'll never complete, I still add to them as much as I possibly can.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
