Worn Dagger

About 1s 0c on Beta · Alliance (1 day ago) and 1s 0c on Beta · Horde (1 day ago), from player scans. A vendor pays 7c, so the auction house pays 13.6× 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 95c there, against 7c at a vendor.
