Tony Love and JG are correct. All the poker clubs in California and casinos around the world that feature poker play by the same rules as far as I know, and the suits are equal for the purposes of deciding the winner of the hand.

The pot would be split if there are two hands of equal value.

Interestingly, though, in the game of seven card stud there is a case when the the suits do have value.

The game begins with everyone receiving two cards face down, and one face-up. Generally, in home games ("friendly" games in people's homes), the highest card of the face-up cards is usually the first to bet, or, if there is a tie, it's usually the "first" of the two, going from the left of the dealer.

But in casinos, the lowest card of the face-ups card is the first to bet, and it's a "forced" bet, called the "bring-in", and it's usually for a lower amount than the minimum bet in that particular game.

Anyway, in a case where there are, say, two deuces showing as the lowest face-up card, the forced bet is determined by alphabetical order of the suits: Clubs first, then Diamonds, Hearts, and Spades.

So in that particular case, Spades does have the highest value so to speak.
