Compare with the physical market
The same card also trades outside Grail. When its market price and the token price drift apart, there are two ways to close the gap:
Not included: marketplace fees (eBay takes around 13%), shipping, and waiting time. Redemptions ship in about five business days, Grail checks eligibility before accepting an item into the vault, and prices can move in the meantime.
eBay shows sold listings only when you're signed in.
No collector holds the 10,000 gCOOP needed to redeem an item yet.
