$43.47
+1.32% over 7 days, $1,221 traded
23 swaps from 20 wallets. Buyers made up 69% of the volume.
171 wallets hold gMJ. Grail's own inventory holds 90% of the supply; the other 10.0%, about $86.8K, is with collectors. The ten largest collectors hold 13% of that float.
Shares of the collector float, excluding Grail's inventory.
Redeeming takes 10,000 gMJ. Grail's price says that's worth $434.7K, but a real trade moves the price. These quotes come straight from the Uniswap pool, fees and price impact included.
Buy a full item's worth
The pool can't supply a full item right now. The largest size it can fill is about 10% of one.
Sell a full item's worth
The pool can't absorb a full item. It runs out of USDC at about $12.6K.

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 gMJ needed to redeem an item yet. Grail's admin wallet holds enough for 1 more; it isn't counted.
Every physical piece behind gMJ, with its grading certificate and the transaction that registered it on-chain. Tap a certificate to check it on the grader's own site.
Supply fully backed. 20,000 gMJ in circulation equals 20,000 minted for 2 vaulted items.
