Ironpatch Blade

About 1g 75s on Beta · Alliance (13 hours ago), 1g 89s on Beta · Horde (14 hours ago), and 1g 60s on Beta · Horde (2 days ago), from player scans. A vendor pays 17s 70c, so the auction house pays 9.4× 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 1g 66s there, against 17s 70c at a vendor.
