Hi, I've recently been given three sealed Royal Mint Cloth bags and was wondering if they have any value above the face value? They are a £100 bag 0f 1968 5 pence pieces, £100 bag of 1970 5 pences and a £5 bag of 1d's. Secondly any ideas how much pre 1919, pre 46 silver scrap coins are worth Thanks for your help Mark
