Sounds like a dungeon key
Do you visit dungeons?

If you visit dungeon and have a key, one will unlock and the key will disappear
If you have two different keys it means you can unlock 2 new dungeons

If you have two of the same keys, i can only say wow go unlock that dungeon and sell the other one

If I'm correct it was this key . Its key to dungeon number 5. Just sell spare key.
