Sports trading cards can be considered an alternative investment opportunity as the market for these cards can be relatively stable (especially following the pandemic) and can offer a potential for high returns. The value of a card is often determined by its rarity, condition, and the popularity of the athlete featured on the card. Some high-value cards have sold for millions of dollars. However, it’s important to note that the market for sports cards can be highly speculative and illiquid, and like any other investment, it carries risk.
