( CNN ) -- Your typical royal toast likely involves a bit of the bubbly . This one just involves some stale bread . Up for auction in the United Kingdom this week is a piece of toast from Prince Charles ' breakfast tray on the morning he married Lady Diana Spencer on July 29 , 1981 . Rosemarie Smith snatched the crispy piece of bread during a visit to Buckingham Palace . Her daughter , who worked for the royal family for almost three decades , had invited Smith to spend the hours ahead of the wedding at the palace with her . `` 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 , '' Smith said in a report on the auctioneers ' website . `` 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 ' ? '' William and Kate 's wedding and the Queen 's Jubilee got Smith thinking that her bit of royal bread could be worth something . `` I just wandered into the auctioneers out of curiosity and asked them if it was worth anything , '' she said . `` I was pleasantly surprised to hear them agree with me that it could be of quite some value to Royal collectors . '' Auctioneer Charles Hanson said he believes the souvenir could fetch up to Â£500 ( $ 778 ) when it goes on the block Thursday . `` If only the toast could talk , '' he said . `` I suspect Prince Charles was a little nervous on the morning of the big day and this little piece of toast survived ! '' Of course , this is n't the first bit of food auctioned off for its unique qualities . Last month , a McDonalds Chicken McNugget that had `` an uncanny resemblance to the undead '' attracted 31 bidders . The zombie McNugget sold for $ 50 . Over the years , a number of folks have claimed to have seen the images of religious figures and celebrities in a host of food items . There was the Virgin Mary grilled cheese sandwich for which an Internet casino site claimed to have paid $ 28,000 . Last year , a couple in Somerset , England , hoped to cash in on a mango-flavored jelly that they said looked like Kate Middleton . Capitalizing on the interest in such items , a company called Burnt Impressions developed a Jesus toaster that burns his image into your morning breakfast routine . Talk about your bread of life !
