Ensure any item you buy comes with a COA from a reputable TPA, not just a random handwritten note.

Before you buy or sell, you must know what an item is worth. Market value is driven by rarity, condition, and athlete popularity.

Counterfeits are common. Professional authentication is the only way to guarantee an item's value and make it "liquid" (easy to sell).

Don't look at active asking prices; instead, search for completed sales on eBay.

Use industry leaders like PSA, JSA (James Spence Authentication), or Beckett (BAS).
