Alot more work goes into pouring silver, Gold, or any metal than one might expect.  With the regulations tight in England UK we are forced to hallmark our pieces at a cost. I have some silver forsale on the classifieds section.  If you do not know how to do the maths, here is a easy way to get a idea of how much it will cost before you buy. Google 60 GBP to USD ( or what ever the cost is) The dollar is very strong now and nearly 1:1 it's the best time for my brothers in America back home to buy UK silver with the guarantee its 100% pure!!!!
