A slice of toast left uneaten by Prince Charles on the morning of his wedding to Princess Diana is going under the hammer in the UK.
Despite being more than 30 years old, the bread — crusts cut off, of course — is expected to sell for more than $760.

The slice was one of several served up to Charles in Buckingham Palace in 1981, as he dressed for his wedding ceremony at St Paul's Cathedral.
The nervous prince couldn't finish his breakfast and the piece of toast was taken as a keepsake by Rosemarie Smith, who was invited to the palace that morning by her daughter, who worked as a royal maid.

"At the time my daughter was a maid at the palace and one of her duties was to collect Prince Charles's breakfast tray from outside his room," Rosemarie told the UK's Sun newspaper.
"I was with her in the corridor and saw that Prince Charles had left some toast on the tray. I had been thinking about a keepsake from the wedding and saw the toast and thought to myself: 'Why not?'"

The quirky item will be sold Charles Hanson Auctioneers, in Etwall, Derbyshire, on July 19.
"It must be the world's upper-crust slice of toast," auctioneer Charles Hanson said. "It witnessed Prince Charles in private on the morning of his big day and to a royalist collector it provides an added dimension to the royalist history."
