Kudos to BJH for a brilliant plot bunny =)
"Remember that currency exchange rates are set by government and banking fiat rather than actual value these days. The Galleon's value against the pound is based on the relative strength of the Muggle and Wizarding economies, not its weight in gold."
But that value cannot be less than the value of the gold or else you end up with people pulling the Witches Secret trick of selling galleons as gold for pounds, then converting the pounds back into galleons and repeating, to get free money.
