Antique baby dish

I believe this was a baby dish for when they learned to feed themselves because of the deep sides. It was my fathers who would be 100. I don't see any chips or cracks. Some discoloring on one side it looks like but in good vintage condition. The sides have a design in gilt. It measures approximately 8 inches across and 1 and 1/2 inches deep. I cant read the bottom but can see a crown and I think the word royal.
