They can be, but cards are a volatile, illiquid asset β not a guaranteed return. Grading helps by authenticating a card and locking in condition, which builds buyer trust and can unlock premiums on high-grade, in-demand cards. But values swing with hobby trends, print runs, and the broader economy, and fees plus buy/sell spreads eat into gains. The safest approach is to buy cards you understand and enjoy, focus on established players/sets and genuine scarcity, and treat any appreciation as a bonus rather than a plan. Avoid over-leveraging on hype. If you're buying purely to flip, study recent sold "comps" carefully and factor in every fee.
