The dish is from the order of Garder, not sure about the specific knit that owned the dish. The coat of arms in on the top of the dish with also the knit crown.
In the bottom of the dish is the order of Garder symbol with the English crown on top, not sure also about the coat of arms, looks like all knits have a different one… Anyway… we want to know how much this will de value and where is the best place to take it… we might need to sell
Thank you ALL!
In the bottom is a mark of the British crown with a JS inscription
In that case this is an important piece of silver and I suggest you take it to a specialist dealer or auction house for a proper valuation. They should also have the time and resources to identify the original owner.
