This afternoon's news that Kate Middleton is pregnant could provide a huge surge in value for her memorabilia, and royal collectibles in general.

We have already seen superb sums achieved at auction following the Duke and Duchess of Cambridge's wedding last year.

PFC Auctions, our sister company, recently sold the first slice of cake from Kate and William's wedding for an impressive £1,917 ($3,085), while the infamous see-through dress which first attracted William to Kate achieved £78,000 ($125,535) in 2011.

The rate at which the good news has spread around the globe this afternoon is evidence of the world's continued fascination with the British royal family, and with a baby on the way, Britain's most famous couple (move over Posh and Becks) are going to be major news for months - or make that years - to come.

You can capitalise on the upsurge in interest today. View our royal memorabilia for sale now.
