the royal baby, that's just the beginning. Ahead, say experts, could be an inheritance of $1 billion.

Add in grandfather Prince Charles ($370 million), father Prince William ($20 million) and uncle Harry ($16 million) and the potential patrimony tops $1 billion.Though tomorrow looks golden, today doesn't look bad. Before the future monach, as he coos and wiggles, lies a cornucopia of delights: bespoke teddy bears, the imperial rattle, a Spode sippy cup, and wee slippers emblazoned with the Union Jack.
