Pagan Vest

About 19s 0c on Beta · Alliance (8 hours ago) and 2g 0s on Beta · Horde (1 day ago), from player scans. A vendor pays 12s 36c, so the auction house pays 1.5× 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 18s 5c there, against 12s 36c at a vendor.
