I’m investing millions in rare sports cards because I see them as a legitimate alternative asset class. When you look at the historical performance of truly unique pieces, some have appreciated far beyond the S&P 500, gold, and crypto. My strategy is simple, build a portfolio of 10 to 20 exceptional pieces, hold them long term, and let them appreciate. For me, allocating 3 to 5% of a portfolio to an asset class like this makes a lot of sense.
