Coin ID

[Deano 0]

Hi, Ive recently bought a job lot of old coins at auction and this coin was mixed in with them, as you can see from the pic, it is a bronzy coloured coin with Victoria Regina dated 1856 on one side and blank the flip side with the letters C + M stamped in it, approx 22mm in dia, Ive looked everywhere to try and ID it with no luck, does anybody have any ideas as to what it is or is it real or fake, would really appreciate some ideas.

Perhaps a gaming token of some sort

The obverse looks like an Austin traders token.
