I have some spare cash that I don't need but not enough to open a new high interest current account with. I sort of want to buy a gold sovereign (£900ish) but there's been a bit of a surge in the price of gold over the last week and now may not be the best time to buy. I think it'd be a nice thing to have, and if in 3 years it has only kept its value I won't be disappointed. Worth the risk? Pointless extravagance?
