UK Babies Born on Same Day as Royal Heir to Get Special Silver Penny

There's a treat in store for anyone in Britain whose baby arrives on the same day that Prince William and his wife, Catherine, deliver a royal heir -- the gift of a coin from the Royal Mint to celebrate the birth.

The silver penny will be dated 2013 and come in a blue pouch for a boy or a pink one for a girl.

To claim the silver coin, UK parents whose baby's birth coincides with that of the royal baby will have to register through the Royal Mint's Facebook page and upload a scanned copy of the birth certificate within 60 days. It is making 2,013 of the coins available.
