I recently came upon what I think is a vintage ashtray from the 50s-60s. I need help identifying the mark on the back. I know "plata 925" means silver 925 and its from my home country Peru. The rest I cannot identify. I think it says " JORKEY" and "1530" any possibility this is from the 1530s? If anyone can give any info on the marks or age id greatly appreciate it. Thank you.
