Gorham Silver Knives have the marks of Gorham - the lion, anchor and ornate G are all raised, as is the Sterling mark, which is in capital letters and encased in a rectangular box. The knives have French blades that do show wear and are in beautiful condition. Gorham silver Knife sets are marked "Gorham Sterling" and have the letter "P" to the right, in a diamond. The "P" in the diamond indicates the size of the piece to be "Place" size setting which indicates that this "P" size was that of a few eights of an inch smaller for the dinner knife and the dinner fork as opposed to the full size dinner knife and fork, or the luncheon size, or the youth size.
Gorham silver silverware of the newer 1904-1950 pieces are marked simply "Gorham Sterling" with the letter "P" to the right in a vertical diamond on the knives and dinner forks. That the "T" in a vertical diamond means the weight of the silver is "Trade" and indicates flatware quality as opposed to mark the five weights used in "Trade, Medium, Heavy, or Extra Heavy".
Gorham silver silverware such as matching teaspoons and the salad/fish forks are consistently the same size with the Gorham Silver Knives which is why they are not marked with the "P". The "P" Place size was one that was usually reserved for the size offered in the bridal registry in department stores.
Many of the amazing and unusual antique Gorham silver knives were made by American silver manufacturers between 1890 and 1925, when a dinner party at home was a major social event. Many classic vintage Gorham silver knives that were en vogue many years ago can be recycled for use on today's table. Antique Gorham silver knives like the master butter knife of course can be used for its original purpose, but it's also an excellent and attractive utensil for serving bagels and cream cheese.
