The Doppelganger Divination Card - Superior Mirrow Arrow 20% Quality (1/2)

I just dropped a Divination Card called THE DOPPELGANGER, which gives after getting another one Superior Mirror Arrow Gem with 20% quality. Do you know how much is this card/gem worth, or how rare it is? (I didn't see card like that in POE.TRADE). SORRY FOR ENGLISH!
