On June 23, Julien's Auctions will sell five historical pieces of cake to the highest bidders at Planet Hollywood Las Vegas Resort and Casino. The sale will come on the heels of the latest British royal wedding, taking place May 19 involving Prince Harry and Meghan Markle.

The five slices up for sale include one from the 1970 wedding of Princess Anne and Capt. Mark Phillips, one from the 1981 wedding of Prince Charles and Princess Diana, one from the 2011 wedding of Prince William and Kate Middleton, one from the 2005 wedding of Prince Charles and Camilla Parker Bowles, and one from the 1986 wedding of Prince Andrew and Sarah Ferguson.

Each cake slice is expected to fetch several hundred dollars, with the piece from Prince Charles and Princess Diana’s wedding reaching as high $1,200. The cake comes inside a white box with silver printing that reads “CD/ Buckingham Palace/ 29th July 1981,” and is wrapped in a paper doily with an original paper envelope bearing Queen Elizabeth’s royal stamp.

Prince Harry and Meghan Markle’s wedding cake will break from tradition. It will be a lemon elderflower cake instead of a fruitcake, which is customary with royal weddings. It will feature the bright flavors of spring and fresh flower decorations, and will be made by pastry chef Claire Ptak, who was born in Inverness, California and now owns a bakery in East London.
