Most private investors cannot manage this kind of top investment so they can be made to invest by buying jewellery or coins in precious metals. The purchase of jewellery and coins has built-in costs connected with that. The markup to get a gold coin is generally between 5-10% to the purchasing cost plus another 5-10% to the selling price, when compared with the spot price of a London Good Delivery Pub. So to get a gold coin investor to only go break even on his investment that is gold, the gold cost needs to increase between 10-20%. For silver and gold jewellery the instance is a lot more sensational as jewellery will cost between 20-100% above the London area gold price that is actual.
