5 grams of silver for £8 is a bargain. You got lucky - hopefully the first time out of many other times. Silver is consumed while gold is hoarded - the reality is going to hit sooner than you might expect. Silver will rise in price, easily into the thousands as time proceeds.
Where can I buy already made silver bars for? I've seen silver bullion, but bars I have not. How much did you say you bought that particular silver bar for? I do believe silver is going to be extremely valuable in the near future which is why I myself am so interested.
That's great glad to see other people coming in and investing in the "white metal" I think it is greatly undervalued! My favorite investment form for silver is the United States silver Eagles. Or the Canadian Maples. They are the easiest to sell and they are in 1 troy once for easy and quick price evaluation.
