While the new monarch is sure to inherit castles and crowns, it can't hurt to teach him a little fiscal responsibility. He can drop his pence into this sterling silver piggy bank from Tiffany's (TIF - Get Report). It will look right at home in any of the family castles.
Perhaps the Queen will sneak him some money from that handbag she always carries. He can then save up his sterling in case he ever needs it for a rainy day. His mom doesn't work and his dad is in the military, so it doesn't hurt to save.
Plus the bank is made of silver so if times got bad he could sell it. This will set you back about $1,900, but it is Tiffany's.
