Sports memorabilia performance 2021

After dipping its toes into positive territory, memorabilia is back in negative territory.

It’s been a dire year for sports memorabilia relative to other alternative asset classes, though it’s worth noting there’s a larger-than-average platform concentration risk here. Nearly 3/4 of memorabilia assets (by market cap) are on the Collectable platform, so it’s hard to say if it’s a Memorabilia Problem or a Collectable Problem.

The average sports memorabilia asset has IPO’ed for around 50% more than its inferred value on Collectable, which may explain the category’s dip in 2021. To get a better feel for it, we could track each asset’s performance starting the day it begins trading, which would eliminate the IPO value as a variable. We’ll try to get to that next week.

Ultimately, we need to decouple the asset class from the platform it’s trading on if we want to get a real feel for how the category is doing overall. It’s definitely worth noting this is true for all asset classes, not just sports memorabilia, and all platforms, not just Collectable.

Last week’s performance

Fractional secondary markets

The George Mikan rookie card photo led the decliners with a 22.2% drop. Another photo, the Ty Cobb photo for T-206, led the gainers with a 17.8% increase. Overall, the market was pretty flat.

All stats come from assets trading on the secondary markets at Otis, Collectable, and Rally

Auctions and elsewhere

Michael Jordan ‘Player Sample’ 1985 Air Jordan 1 Sizes 13 & 13.5 (Sotheby’s Icons of Excellence and Haute Luxury)

  • Sold for $100,800 (pre-auction estimate of $50,000 – $70,000)
  • A similar pair of shoes, but signed by Michael Jordan in his rookie year, is currently trading on Otis for $67,500.
  • Jordan’s signature from around his rookie year has added approx. $60,000 in value to his 1986 Fleer rookie card (Michael Jordan Autographed Rookie Card).
  • Inferred value of Otis asset updated to $164,000.

1995 Derek Jeter Minor League Game Used & Signed Columbus Clippers #13 Road Jersey (Goldin Elite Auction October 23 – 24)

  • Sold for $27,060
  • Rally has a similar jersey, but from one year earlier in 1994, that is also game used and signed by Jeter which last traded at a $30,200 market cap.
  • Jeter switched jersey numbers from 1994 to 1995.
  • I would expect the 1994 jersey to trade at a slight premium due to the older age, but otherwise the Goldin offering is a good comp for the Rally asset.
  • Maintain inferred value of Rally asset at $39,000.

1971-72 Roberto Clemente Game Used, Signed & Inscribed Hillerich & Bradsby U1 Model Bat – (Goldin Elite Auction October 23 – 24)

  • Sold for $118,080
  • Both Rally (1959/GU 10/market cap = $50,000) and Collectable (1965 & 66/GU 9/market cap = $56,952) offer game used, but unsigned Clemente bats.
  • Both are from earlier years in Clemente’s career; the Goldin offering is later, but is from his final seasons (including the season of his 3,000th hit) and has a personalized autograph.
  • Strong result that is influenced by the high grade (GU10) and autograph.
  • Recent comp sale for the Collectable offering cause inferred value to decrease to $24,000 (1965-68 Roberto Clemente Game Used Hillerich & Bradsby U1 Model Bat (PSA/DNA GU 9)

Notable Items

1974 Hank Aaron Batting Helmet Game Used for Record Tying Home Run (Goldin Elite Auction October 23 – 24)

  • Sold for $221,400
