Summary
Gordy Bonker says he turned a side hustle into Bonkers Cards after leaving a traditional corporate path in sales and recruiting, and he frames vintage sports cards as both a passion and an investment category. He argues that premium cards like the 1952 Topps Mickey Mantle and T206 Honus Wagner sit in a different league from modern issues because the vintage market is scarcer, less efficient, and more dependent on grading.
He compares long-term price appreciation in select cards to the S&P 500 and says the best examples can rival or exceed stock-market returns, especially in low-population high-grade copies. He also explains how PSA, SGC, CGC, and Beckett differ, why grading can dramatically change value, and why buyers should only grade cards that are likely to clear the fee and have real post-grading upside.
Beyond investing, Bonker emphasizes the hobby’s community and media flywheel, pointing to the National Sports Collectors Convention, TikTok live shows, and the influence of Fanatics, Topps, and collector media. He closes by discussing his mental-health struggles, his support for Movember, and how his wife Amanda backed his move into the hobby business.
Key takeaways
- Gordy Bonker says vintage cards, especially high-end 1950s and earlier issues, are better alternative assets than modern cards because the market is more scarce and inefficient.
- Bonker says the 1952 Topps Mickey Mantle is the “Mona Lisa” of sports cards and believes even a low-grade copy can outperform the S&P 500 over time.
- He says grading can create huge valuation gaps: a lower-grade Babe Ruth card may be worth $5,000 to $6,000, while a high-grade example could reach $500,000 to $1 million.
- Bonker says PSA remains the market leader, while SGC is his preference for presentation; Beckett has fallen behind except in some niche categories.
- He says collectors should not grade cards unless the card is likely worth at least $50 and the expected post-grade value clears the grading fee by a wide margin.
- Bonker says the hobby’s next growth leg will come from content, events like The National, and a younger audience rediscovering cards through social media.

How the episode opens
Welcome to the Bangers Only podcast, where Tom Leiden and his band of experts make money talk exciting. Here's your host, Tom Leiden. Welcome to the Bangers Only podcast.
Life is short. We've got to keep things simple. That's what Bangers Only is all about.
I'm Tom Leiden and I'm thrilled today to have a special guest, Gordy Boner, who's the creator founder of Bonkers Cards. Uh he specializes in vintage collectible cards. Gordy, it's such a great pleasure to have you with us today.
Yeah, Tom, thank you so much, man. I've been looking forward to this. I'm stoked to get to uh come on the pod, talk a little bit about sports cards, maybe mix it up with some investment talk.
I'm here for it, man. Well, talk a little bit about what you do and and this was kind of a side hustle for you that's developed into something full-time. Walk us through that if you would.
Definitely. Well, there's a lot that goes into it, man. I guess, you know, prior to going full-time and uh pushing all in on bonkers cards, I had a pretty traditional career path.
You know, I worked uh graduated from Penn State's business school in 2018. Worked in very traditional corporate sales roles. Uh my last couple years in the corporate world, I was a basically a head hunter in New York City for financial services firms, primarily within investment banking, private equity, and hedge funds.
And while I was doing that, I was creating a lot of content. Um, I had a podcast. I was doing a lot of short form video content using Tik Tok, talking about the job market, stock market, economy, and that was a great way to attract uh clients, good candidates.
Um, you know, it gave me a lot of credibility in the market, having a platform, and obviously showing that I was knowledgeable about the subject matter these people were working in.
