We ultimately sell them to contacts in the jewellery trade, or sell them as coins by weight to private investors. Pre 20 sterling is more useful as it's already sterling so can be make into jewellery as it is. I suppose some coins may end up polished to within an inch of their lives and in those fancy-birth-year sets in plastic folders or sold to tourists, but to actually get good money for bog standard pre 47 silver you have to have an awful lot of patience! I move it on quickly after a small cut and then hope that some actual collectable coins will come along! I must have handled tons and tons of pre 47 over the years.
