Tokens (Garbage Dwarf)

From LSWiki

As an easy way to quickly rid yourself of garbage you've collected, your portable litter disposal unit is capable of squashing everything inside and producing a single coin from it all. These coins can be turned into Hank for a few gold coins. Fear not, if you happen to suddenly leave the realms before turning them in, as they will find their way back to you whence you return.

And remember, the more tokens you hand in, the better the possibility of more, and bigger, rewards!

(Do take the coins into your inventory before logging out. Seems they will not "find their way back" if they are still inside the unit.)
