I came across this coin opp charity collecting machine on the promenade at Herne Bay, Kent, last weekend.
Originally designed and built by the members of the Herne Bay Rotary Club in 1967 this is the third major rebuild completed in 1983 with minor revamps along the way. Any denomination of coin will run the machine and in recent times over a summer it is estimated that 350,000 coins are dropped into the slot raising around £4,000 for charity.

I would love to have a look inside it.
