There is something almost stubborn about the way Marcus Hale talks about his collection. He keeps the cards in a temperature-controlled cabinet in the back room of his Paddington townhouse, each one sleeved in a plastic case stamped with a PSA grade. He is not a nostalgic man, not particularly. He did not grow up watching American baseball. But he has been quietly building a portfolio of authenticated vintage cards for the better part of six years, and in 2025, that decision started to look less eccentric and more deliberate.
Hale is the kind of investor Brisbane tends to produce in modest numbers — methodical, slightly contrarian, deeply skeptical of anything described as “the future of finance.” When Bitcoin was climbing past eighty thousand dollars and influencers were evangelising Dogecoin on social media, he was attending card grading expos and reading auction reports from Goldin and Heritage. It’s possible he looked foolish then. He does not look foolish now.
In 2025, a 1953 Mickey Mantle baseball card outperformed Dogecoin by roughly 75%. That number sounds invented, but it isn’t. Research published by David Krause, an emeritus finance professor at Marquette University, tracked a basket of 15 investment-grade vintage baseball cards across the year and found the index returned just over 15% with annualised volatility of around 10.5%. The same period saw the top-ten altcoin index fall more than 32%, with volatility exceeding 57%. By any standard risk-adjusted measure, the cardboard won.
Hale had not read the study when we spoke. He had arrived at similar conclusions through a different route — watching his own collection hold value through two distinct market stress events in 2025, an April tariff shock that rattled equity markets and an October crypto deleveraging cascade that wiped out enormous altcoin positions. “I watched people lose thirty, forty percent in a week,” he said, not smugly, just observationally. “My cards didn’t move much either way. That’s the point.”

This is what makes vintage sports cards interesting as an inflation hedge, and it is not quite what people expect. The argument is not that cards generate income or compound aggressively. The argument is that they tend not to move with everything else. The Marquette research found near-zero correlation between its baseball card index and the S&P 500, and a slightly negative correlation with altcoins. In a year when traditional diversifiers were failing investors, authenticated cardboard was quietly doing what gold is supposed to do.
There’s a sense, walking through card shows in Brisbane or Sydney these days, that the market has matured somewhat from the pandemic-era frenzy, when raw ungraded cards were selling at inflated prices and the hobby attracted a wave of speculative buyers chasing momentum. That correction happened. It was uncomfortable for some. What remained after the hype faded was a smaller, more serious segment of collectors and investors who understood the difference between a PSA 8 and a PSA 10, and why condition determines nearly everything about long-term value.
Hale focuses almost entirely on pre-1970 American baseball cards — Hall of Fame players, rookie issues, and star cards in documented high grade. He is patient in a way the crypto market does not reward. He expects to hold each card for at least five years. The transaction costs alone justify that patience, since round-trip buying and selling in this market can cost around 15% once auction fees and authentication charges are factored in. That is not a market for traders. It is a market for people who think in decades.
It is still unclear whether this kind of allocation belongs in every serious portfolio. The liquidity constraints are real, the tax treatment is complicated under Australian rules, and the market is thin enough that it cannot absorb large institutional money without distortion. But for a private investor with a five to ten year horizon and a desire for something genuinely uncorrelated to equities and digital assets, the case is more coherent than it sounds. Hale put it simply: “It’s not going to zero. It can’t be hacked. And people keep caring about Mickey Mantle.” That last part, oddly, might be the strongest argument of all.
