I found 3 of these in my shop and when I went to price them I noticed there are none in the trades or the user shops. Does anyone know what they're worth? Thank you!

It's an newish melody item... 2013-4 I believe. There should be plenty more someone is hoarding since it's given as a free item during the time of year subeta have the most users. Just throw it at the shop for 100m and see if any item hunter or collector gets it. However, it will devalue a bit fast since people will start to undercut you before you get the chance to sell it. Good luck!

Thanks for the advice!
