Same as in Classic Era.
About 15c on Beta · Horde (5 hours ago), 15c on Beta · Alliance (1 day ago), and 15c on Beta · Horde (1 day ago), from player scans. A vendor pays 15c, so the auction house pays 1× more.

Sell it to a vendor. A stack of 10 brings 1s 50c there — more than the auction house nets after its 5% cut.
There's no auction house to price until then.
