Basketball card collectors will spend big to secure two types of rare cards, vintage cards in perfect condition and low-numbered modern cards of NBA superstars. A list of the most expensive basketball cards usually involves both. At the top of the list is the first true pro basketball superstar.
George Mikan rookie cards and other rarities picturing the former Minneapolis Lakers sensation command some of the biggest prices. In December of 2009, one of his 
cards sold for $218,550 at a Memory Lane Inc. auction. Not only was it his rookie card, but it was in the same condition it was when it was made. The card was the 1948 Bowman #69 George Mikan, with a grade of PSA GEM MINT 10. Any Mikan rookie is valuable, and on eBay his rookie card with a grade of PSA EX-MT 6 sold recently for $3,063.23.
Any complete sets that have a Mikan card go for big money, but there are probably more collectors that want the Mikan cards than the full sets. Not only was Mikan in 1948 Bowman but in 1948-49 Exhibits Sports Champions, 1948 Kellogg’s and 1950-51 Bread For Health and 1951 Bread For Energy. As these are bread labels there will be very few in high grade, but when they do appear in as-new condition they go for strong prices. Two Bread For Health Mikans sold in 2012 with low grades. A George Mikan graded SGC 20 FAIR 1.5 sold for $1,279.25 at a Mile High Card Company auction and another sold at SCP Auctions, that was graded SGC FAIR 20 and sold for $1,172.00.
Michael Jordan cards can obtain high prices. Selling for $13,000 on eBay in 2012 was his 1984-85 Star #101 extended rookie card, with a grade of BGS 9 MINT. That card and his Fleer 1986-87 rookie card often have the highest values.
Fleer Jordan rookie cards have been rising in value on a steady basis despite tens of thousands in the market or in personal collections. High-grade Jordan cards have proven to be very good investments.
However, collectors can actually open more recent packs and find expensive Jordan cards, too. One example of this was his Fleer Retro autographed 1997-98 E-X Jambalaya Buyback. The bidding went up to $29,299.69 in the fall of 2012, as this card is a 1 of 1.
Buyback cards should continue to bring strong prices, especially Jordan cards like his 2001-02 Ultimate Collection Buybacks. Michael Jordan autographed older Upper Deck cards, and these along with an accompanying certificate were in the Ultimate Collection packs. There are 1 of 1 cards, and others with only two or three ever made.
There are also graded rookie cards of Chamberlain, West, Russell and other superstars that go for hundreds–sometimes a few thousand dollars in ultra high grade. A Larry Bird-Magic Johnson rookie card–which also includes Julius Erving from the 1980-81 Topps set was graded PSA 10 GEM MINT and sold for $16,000. PSA 7 examples sell for around $175 with 8’s at about $400-500.
The most expensive basketball cards typically involve high grade rookie cards of the game’s greatest icons.
