How do I use coins?

Thanks for the help.

coin is a word that is overused in Subeta. Can you be more specific?

There's a coin machine in the lower side of centropilis (likely spelled that wrong) Just select the coin(s) and enjoy the random reward

Thanks! ;D

It's the item 'Copper Special Coin'

Yes, what said is correct then. x special coins (where x= some color or metal) go to the coin machine in the lower west side of centropolis . It must be special coin to work there.

There are other coins that are for the gym vending machine, for the vesnali holiday, WT are (odd shaped) coins that go many places, and there are morostide candy coins to eat, and Coin of the (chinese zodiac) which are wearable, etc.
