W is the joker, and it is wild. Hold it with K♠ Q♠ J♠ and either the 10♠ or the A♠ completes a wild royal paying 100; the 9♠ makes a 50-coin straight flush; six more spades make an ordinary flush anyway. Nine of the 48 unseen cards keep the spade hand alive, two of them for twenty times the 5 coins the pat flush hands you. The awkward part is that the joker is doing the work in both hands — it is already a spade for flush purposes, which is exactly why giving up the made flush costs so little.
