The Card: Because the Sport Kings set is desired by collectors of various sports, all the cards, including this Nat Holman, have retained their value. Many basketball card collector’s consider this the first basketball card since it predates the landmark 1948 Bowman set. In the 1920’s Nat Holman was considered a phenomenal shooter and ball handler, but the game was drastically different from what we know today. Note Holman’s book Scientific Basketball mentioned on the back of the card. Read it here and you will be amazed at the differences! The 2001 Standard Catalog of Basketball Cards lists a Near Mint at $950, a NM/M at $3000 and a Mint at $4000. The near mint might be reasonably accurate. Ungraded cards sell for an average of $50, but high grade cards are always increasing in value. A PSA 8 sold for $24,766 on September 19, 2016 (eBay item 351835044587). Only twelve exist at this grade, none higher.
In Short: Landmark card and good investment!
