Heavy Bronze Mace

About 60s 0c on Beta · Horde (5 hours ago), 59s 0c on Beta · Horde (22 hours ago), and 74s 0c on Beta · Alliance (23 hours ago), from player scans. A vendor pays 27s 41c, so the auction house pays 2.1× 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 57s 0c there, against 27s 41c at a vendor.
