Now is your chance to own a piece of edible history.

A slice of the fruitcake from Prince William and Princess Kate’s 2011 wedding is going up for auction. The 3-year-old confection will be sold on Dec. 5-6 through Julien’s Auctions Beverly Hills, during which a collection of the late Princess Diana’s dresses will also be on the bidding block.

The cake will be packaged in a decorative gold tin and will include a blank wedding invitation written on Queen Elizabeth‘s stationery. So, what is the expected price tag? The opening bid is $500, but it could reportedly fetch anywhere from $1,000 to $2,000.

This isn’t the first time the famous 9-tiered fruitcake — made by pastry chef Fiona Cairns — has been dished out since the royal nuptials. Princess Kate and Prince William kept the top three tiers and served the top layer during Prince George‘s 2013 christening. You can make the famed cake at home, with Cairns’s own recipe.

Maybe the royal family is saving the second layer for baby number two?
