Hello! Hoping someone can help me. My great grandmother had this Mayell gold plated shell butter dish that I received after she passed away about 15 years ago. I recently came across it again when I was cleaning out the house and out of curiosity decided to look it up to see what it was worth. Thing is, I can't find a gold plated Mayell shell butter dish anywhere! I see lots of information about the silver plated ones, but I can't even find mention of the gold plated. It looks like there were very few made (there's a sticker on the box that says 74/141 so I'm not sure if 141 is all that were made?). It says 24 karat on the box as well. I've attached a few pictures if that helps. Anyone have any idea what this is worth?
