I have a sterling marked youth spoon, 5 1/4", and on the shoulder facing the bowl are 3 marks. I can't decipher the first, the next is 925/1000 the last is made up of the initials P R in elegant and simple script. I have search around and can't find anything like the top mark. Does anyone recognize this? I've included a closeup of the first mark.
Thank you so much for your help!
