I found these coins in a plastic bag in a pacage containing 4 volcanic rocks picked up in Lanzarote about 8 years ago. Why they were in with the rocks is a mystery. They are all recent coins actually, the oldest is dated 1965. Most are the UK new decimal coinage which was introduced into circulation on 15th February 1971. I think there has been a reaction between the metals and the rocks.
