Zion Williamson heads up the list of the athlete with the biggest price drops. But over time, we have seen many cards fall from grace.

 

 

The worst sports card investment ever isn’t just one card — it’s more like a category of cards that symbolized the market’s collapse due to overproduction and misplaced hype. That said, here are the most infamous examples:

🚫 1. 1990s Junk Wax Era Cards

🔥 Example: 1990 Donruss Ken Griffey Jr.

  • Printed by the millions.

  • Once thought to be a future fortune-maker.

  • Still sells for less than $1 ungraded today.

  • Even PSA 10 versions are barely worth the grading fee.

Why it was bad:
Massive overproduction and a false sense of scarcity. Collectors hoarded boxes, but the supply far exceeded demand. Many cards from this era (1987–1993) are virtually worthless today unless in rare condition or error form.

😬 2. Overhyped Prospects Who Flamed Out

Example: Ryan Leaf Rookie Cards (1998)

  • Drafted #2 behind Peyton Manning.

  • Prized as the “next big thing” in 1998 sets like SP Authentic, Topps Chrome, and Playoff Contenders.

  • Career: 25 interceptions to 14 TDs; out of the NFL in 3 seasons.

  • His rookie autos were once hundreds of dollars, now worth under $10.

Other infamous busts:

  • Todd Van Poppel (baseball)

  • Greg Oden (basketball)

  • Mark Appel (MLB)

  • Zion Williamson? (Still debated...)

💸 3. Overpaid for Modern Graded Base Cards

Example: 2019 Prizm Zion Williamson PSA 10

  • During the COVID boom, PSA 10 base Prizm Zions sold for $800–$1,000.

  • By 2024–25, they dropped to $80–$100, a 90%+ loss.

  • Base cards became overvalued due to false scarcity in the grading frenzy.

Why it was bad:
Too many people graded base cards expecting guaranteed value. But base Prizms were mass-produced, and pop reports exploded.

💀 4. NFT or Digital-Only Sports Cards

Example: NBA Top Shot (2021)

  • Some moments (like a LeBron dunk) sold for $200,000+.

  • Many have plummeted by 95–99% in value.

  • Little long-term collector interest or scarcity.

Why it was bad:
It was fueled by hype, FOMO, and speculation rather than collector fundamentals or physical ownership.

🤯 Honorable Mention: 1991 Fleer Baseball Yellow Cards

  • Universally disliked for the design.

  • Mass produced. Poor quality control.

  • Almost zero resale value.

  • The Bobby Bonilla of card sets—it lives on ironically.

🔑 Lessons from the Worst Investments:

  1. Scarcity matters – Not all rookies or shiny cards are rare.

  2. Hype fades – Base card hype, especially during boom cycles, rarely sustains.

  3. Prospect risk is real – Many highly drafted players flop.

  4. Stick to GOATs or true scarcity – Jordan, Brady, Mantle, Ruth, low-serial parallels, and on-card autos hold value better.

 

 

 

 

 

One of the clearest examples of a sports card that turned into a terrible investment is the 2019–20 Panini Prizm Zion Williamson base rookie card in PSA 10.

📉 Zion Prizm PSA 10: A Price Collapse Example

Historical Highs:

What It’s Selling For Now:

  • As of March–April 2025, recent PSA 10 auctions have only pulled $200–$400, often dipping all the way below $250 .

  • Current data shows the last sale around $216 in late March 2025 psacard.com.

📊 Market Trend Comparison

CardLadder reports:

  • A PSA 10 Prizm Zion sold for just $33.57 as of mid-May 2025.

  • Total population exceeds 23,000, yet the market cap sits around $776k .

This illustrates a ~97%+ loss from peak pricing in a span of about 2.5 years.

🎙️ What the Community Says

This decline mirrors broader trends seen in assets like digital sports collectibles (e.g., NBA Top Shot), where hype-driven supply triggers massive value swings psacard.com+5reddit.com+5reddit.com+5.

💡 Why This Was a Bad Investment

  1. Lack of true scarcity – Over 23,000 PSA 10 copies exist.

  2. Hype-driven valuation – Prices soared during boom times, unrelated to rarity.

  3. Misunderstanding market fundamentals – Many graded base rookies hoping for sustained lifetime value.

✅ Bottom Line

  • Buying PSA 10 base Prizm Zions at $1,300+ was extremely risky—now it's trading for $200–$400, or as low as $33 raw.

  • When investing in modern cards, scarcity + collectability matter more than hype.

  • Avoid mass-graded base cards as investments; focus instead on low-pop parallels, on-card autos, or rookies of enduring stars.
