Same as in Classic Era.
About 18s 0c on Beta · Alliance (2 hours ago), 7s 0c on Beta · Horde (8 hours ago), and 8s 0c on Beta · Horde (1 day ago), from player scans. A vendor pays 50c, so the auction house pays 34.2× 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 17s 10c there, against 50c at a vendor.
There's no auction house to price until then.
