You can have a piece of Prince William and Kate Middleton's wedding day if the price is right.

Days after the royal couple celebrated their first wedding anniversary, a slice of their wedding cake is up for auction online, where it is expected to fetch as much as $1,500.

The slice, believed to be the first up for auction, is from the multi-tiered, traditional fruit cake that the Duke and Duchess of Cambridge served to guests at an afternoon reception at Buckingham Palace on their big day. Each of its layers was adorned with white icing and 17 varieties of of 900 iced flowers and leaves, according to cake designer Fiona Cairns, who spoke to ABC News at the time.

The piece of cake comes in the white and gold presentation tin that was given out to 650 guests at the luncheon that day. A printed note from Prince Charles and the Duchess of Cornwall and the 16 page Order of Service from Westminster Abbey, which includes the vows, hymns, prayers from the ceremony, are also included.

"We anticipate worldwide interest," Kylie Whitehead of PFC Auctions, the online auction house offering the cake, told the U.K.'s Sun. "We believe that this is the first piece of William and Kate's wedding cake to appear at auction. … It's a fantastic opportunity to own such a personal piece of memorabilia from the future king and queen."

The seller's identity has not been disclosed. Bidding starts at £100, or approximately $160, and runs  through March 24, according the PFC Auctions website.

Cake from the 1973 wedding of Princess Anne and Captain Mark Phillips is also up for auction, as well as the 1981 wedding of Prince Charles and Princess Diana. In 2008, a buyer paid $1,830 for an elaborately decorated, 9-inch-square piece of cake from Charles and Diana's nuptials. The royal dessert came with a signed thank-you letter from the couple.

If a piece of stale cake for $1,000 is not in your budget, you can actually re-create the royal wedding cake in your own home. Cairns shared her recipe with ABC News last year. Click here for the instructions.
