Wanting to bring a gift

Hi everybody,

First trip coming up to japan here shortly! Beyond excited for sure 😊

I have a ring making class scheduled where my fiance and I will be making silver rings. I have a silver coin, u.s. minted that I would like to gift to the shop. Is this a bad idea? I dont want it to be perceived as a tip, but thought that since they work with silver it would be a cool piece of US silver..

Idk, is that strange? Haha thanks everybody, any advice on presentation or etiquette would be appreciated
