Bought in 1970s and used many times. There is wearing to the coating and scratches consistent with use, please see photos. Also some denting again please see photos. In my view any denting is no obvious when the food is turned out
The mould is tin with a copper coating. I am unsure if it is copper or a copper colour. I have other dessert and fish moulds which I will be listing bought around the same time. Please message me for further information
