I finally just received an Adelaide Casino coin/token from their first birthday which I've been looking for for a couple of years. I know nothing about coin metals etc & know that as a rule you shouldn't clean coins but as this is a commemorative casino token I figured it doesn't matter. It's in new condition with some slight tarnsihing but still has a nice lustre. I was wondering what to use to clean it up bright & sparkly again? I don't know what alloy it is but it looks very coppery???!!! Thanks for your help guys.

Cheers, Tim.

This is the same one but mine has a much newer look.
