Severed Talon

About 1s 2c on Beta · Alliance (3 hours ago), 98c on Beta · Horde (9 hours ago), and 98c on Beta · Horde (1 day ago), from player scans. A vendor pays 96c, so the auction house pays 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 5 brings about 4s 85c there, against 4s 80c at a vendor.
