This is a much rarer Royal commemorative - made in 1888 to celebrate the 25th Wedding Anniversary of Edward VII (then the Prince of Wales) and his Danish wife, Alexandria.
It is much more common to find items of this type celebrating his coronation in 1902 - and these earlier pressed glass plates for his Silver Wedding celebrations are much rarer.
It is a lovely shallow bowl that measures 8 1/2 inches square - and has a height of 2 3/4 inches.
Unpacked it is about 600 grams in weight. To post safely to you, the final packed weight will be about 2kg.
As you can see from my photographs - it is certainly a very attractive piece of antique Royal memorabilia - the plate reads: Prince and Princess of Wales / Britons' Hope and Joy. The three feathers symbolizing the Prince of Wales are in the center - and below the words: SILVER WEDDING. Dates are to each side.
I have photographed both the front and back for your inspection.
The glass is pressed with little hobnail texture - and this helps it twinkle in the light.
It is in good antique condition with no cracks or nasty chips - a beautiful and rarer display piece.
Fair price for a harder to find Royal souvenir. I have another variant on this design on offer in my Iconic Edinburgh online store.
