Hello there. I just finished up the achievements to fish up the coins in Dalaran. I received the Titanium Seal of Dalaran via the mailbox and flipped it once. Now the item no longer exists in my inventory. I read via Wowhead that the item is not a one time use item, so something had to of gone wrong.

That being said, i seek to have my Titanium Seal of Dalaran restored else is there another way I can go about getting it back in game?
