I went to a specialist and had the fork tested by a pro. He said it was indeed a platinum hallmark... the "950 in an Upside-Down Shield" is an English hallmark representing 95% platinum... but this is not a platinum fork. By sheer coincidence the French produced a hallmark called the "Obus" or "cannon shell" which looks identical to the English "House" or "Upside-down" shield. This "cannon shell" mark was placed only on exported French silver and the silver purity number (e.g 800, 925, 950, 999) could be stamped anywhere near it. In a horrible coincidence Cartier thought it a good idea to stamp the silver purity number inside the "cannon shell" instead of next to it - resulting in their 95% Silver having a near identical hallmark to English 95% Platinum. So this is, as many have suggested, just a gold plated 95% silver fork. I would not have posted this as "platinum" if I hadn't been so certain, it was a one in a million fluke. I hope you can all forgive me...
Furthermore the "PT" before the 950 is in fact an "R" as I initially thought, and the "M" apparently represents the 5% copper within the silver. The guy said it is worth $40-$50. No $2500 dinner for me anytime soon oh well ^^ ...but I guess a gold and silver fork is still just a bit more fun to eat with than a plastic one.
