What value as regards pre 1947 silver coins if any as scrap?
No matter what country you are in, the system is about the same. Silver coins that are low grade, damaged or have high mintage’s are bought and sold as per the ASW which is actual silver weight. It depends on what the spot price of silver is the day sold. A dealer buys for a percentage less that spot and resells them for a percentage above spot, or has them melted where he makes less. On coins of the UK up to 1920 the silver coins were .925 silver, then went to .500. So a six pence had .0895 oz of ASW in the ones dated 1920 and before and after that .0455 oz of ASW. You need to find a coin dealer that has the ASW for all the UK coins. They are listed under the coins in Krause/Mishler Standard Cataloges of World Coins Hope this puts you on the right trail.
