Would you buy a slice of cake for $1,375? Well, somebody did.

The 33-year-old cake was from the wedding of Prince Charles and Princess Diana in 1981. The cake is still in its "original white and silver presentation box" when it was sold online." The cake was sold by Nate D. Sanders Auctions of Los Angeles.

The box has the Prince of Wales feathers and bears the monogrammed "CD." It also came with a card that says, "With best wishes from Their Royal Highness, the Prince & Princess of Wales."

According to Sam Heller, a spokesman for the auction house, the buyer was a private collector of cakes. The cake is possibly not edible even though it is still wrapped in the original wax paper. Mr. Heller also added that there is a small group of royal cake collectors that bids when opportunity like this arise. There are also some collectors who bought cakes dating back to 1840's.

Another cake was from Prince Charles and Princess Diana's wedding and it was sold for £1000 back in 2008. The cake was bought by an anonymous buyer. According to the Telegraph, the cake was given to Moyra Smith who was a member of the late Queen Elizabeth House, the Queen Mother's household at Clarence House. Smith managed to preserve the topping in an icing film and she kept it inside a metal tin.

The Telegraph describes the cake as a "nine-inch square piece of icing and marzipan weighs 28 ounces, bears the royal coat-of-arms and is coloured in gold, silver, red and blue."

Royal cakes are a part of history. Maybe that is why the collectors collect it. It makes them feel like they are a part of the culture and the history. Maybe in the long distant future, this will serve as one of the last remnant of the royal family.
