A 77-year-old piece of wedding cake from Queen Elizabeth II and Prince Philip’s wedding has sold for £2200 (USD$2800).

Sold by auction house Reeman Dansie, the piece of cake – which no longer looks edible –  was sold in the box with original packaging, alongside the presentation card.

The packaging was addressed to ‘Miss Polson, Palace of Holyroodhouse, Edinburgh, Scotland’, and was postmarked April 21, 1948. Alongside the cake was a printed letter from HRH Princess Elizabeth thanking the royal household staff for their wedding present.

“My husband and I are both deeply touched to know that you shared in giving us such a delightful wedding present. We are both enchanted with the dessert service; the different flowers and the beautiful colouring will, I know, be greatly admired by all who see it,” the note read.

“This is a present which we shall use constantly, and whenever we do we shall think of the kindness and good wishes for our happiness which it represents. Your generosity will also enable us to buy at leisure something else which we shall need and for which we send you our grateful thanks in advance.”

Miss Polson was the housekeeper at The Palace of Holyroodhouse from 1931-1969.

The royal wedding cake stood 2.7m tall and weighed approximately 500 pounds. It was decorated with the coats of arms of both families as well as sugar-iced figures of the couple’s favourite activities. Almost 2000 slices were served to guests and it’s thought hundreds more were sent to charities and other organisations. One tier was kept for the christening of the then-Prince Charles.

A few of these wedding cake slices have survived the years. Another was sold at auction in 2013, fetching £1750.
