Anyone know what this might be worth? There's no overall price or any in the shop search...

According to Subetalodge it's a brand new release. It's Super Rare, but restockable. You can start it out at pretty much whatever price you want, unless someone is desperate to get it before more come out on the market I don't know how well it will sell.

Thanks, doll! Maybe I'll just throw it in my shop then (:
