Crocolisk Meat

About 50c on Beta · Alliance (5 hours ago), 16c on Beta · Horde (11 hours ago), and 18c on Beta · Horde (1 day ago), from player scans. A vendor pays 16c, so the auction house pays 3× more.

1 recipe: Crocolisk Steak.

It exists in Classic Era too, but with different numbers there.

Sell it on the auction house. After the 5% cut a stack of 20 brings about 9s 50c there, against 3s 20c at a vendor.
