Help identifying silver hallmark stamp


I have been gifted a set of silver sups and I am hoping someone can please help me identify this silver stamp. It is a six-pointed star with an “S” in the centre i believe, with what looks like NS below and then the number 35 under that. It belongs to a set of 3 nesting cups that have a leather holder. Please if anyone has any input on their value also, i would be very grateful. Thank you!

Hello, I’m sorry to inform you but the item you posted is not solid silver, it’s just silver plated. The NS is probably Nickel Silver, you can even see below the difference in appearance of the part where someone threw acid. The item’s brand symbol is the S inside the star.

Thank you kindly for this info, very helpful and appreciated. Cheers, Alisa
