Your expected value is -$0.62.
We multiply the probability of winning by the amount won. There are 12 face cards out of 52 cards, and the amount won is 4:
12/52(4)
We also multiply the probability of losing by the amount lost. There are 40 cards that are not face cards out of 52, and the amount lost is 2:
40(52)(-2)
Adding these, we have:
(12/52)(4)-(40/52)(2) = -0.62.
