Don't worry about wasting it. It won't wear off if the treasure chest is open or if you're not wearing it(by this I mean saying the magic words)or if you're at the wrong chest. So, just wear it as a magic pin and use it as a magic pin. In front of the correct chest. If you've got any doubts on which chest it is, just go to the Pirate's Treasure Room(to the left of POTC Game Lobby)and ask where the Bronze treasure is located.
That happened to me six times in a row on each of the three chests. THEN I got a 500 credit one, which really stinks. I don't want credits! I want exclusive prizes! If I wanted credits I'd play Fireworks!

Here's how to open a chest with a key. You go up to the right chest, and is you have a bronze key, say YoHoBronze! or click the wand button, for silver say YoHoSilver!, and gold YohoGold!
i play pirates a lot and i got into the high score like two times in ship battle. but i wonder how do you get the top ten high score pin? i saw someone wearing it.
