FREE: Let's Play A Game! Mass Auction!

The listing, Let's Play A Game! Mass Auction! has ended.

Went to an Estate Sale and purchased a box that had these in a zip lock bag inside it. Not familiar with anything related to this but am sure some of you are. This is a Winner Takes ALL. ALL Listia's rules apply. Below is the Mini-Game info. Please no negativity and have a happy bidding! :)
P.S.Will do GIN a bit later.

Surprise Mini-Game!!!
I saw this being done by some Listia's members and so I wanted to join in. This is a guessing game and in order to win you will need to guess the surprise item correctly. Once the winner is decided, I will then get into contact with them to receive shipping information to ship the surprise gift. I will give a hint if the guessing gets way off and I will also give 2 starting hints! Pay attention to the comments to see what's guessed and have fun! :^)

HINT 1: I am in the "shape" of something loud, but nowhere near the size of a cloud. I'm small enough to be held in your hand but when I'm hung, I'm "twice that man". I'm made of solid brass as plain as you could see, can you guess what I was described to be?

HINT 2: I'm NOT an earring. Lol. :^)
