This may be old news, so apologies in advance, but there is no Trident Token among the Tokens sold by Glory vendors in the Mists; it was supposed to be between the Torch Token and the Warhorn Token (at least this applies to the Rank1 and Rank10 ones, which I’m able to check).
This problem has been going on for several weeks now, though I guess not many care about forging PvP Tridents.
