About 90s 0c on Beta · Alliance (20 minutes ago), 1g 0s on Beta · Horde (45 minutes ago), and 49s 0c on Beta · Alliance (4 hours ago), from player scans. A vendor pays 5s 0c, so the auction house pays 17.1× more.

No. It is in Classic Era too, with the same item level, vendor price and stack size.

Sell it on the auction house. After the 5% cut a stack of 1 brings about 85s 50c there, against 5s 0c at a vendor.
