Hello
I have Lenox teacup set, which made of 12 ceramic cups and silver saucer. Under ceramic cups, it says Lenox and displaces Lenox logo. On the bottom of silver saucers, it says;
"mark"
STERLING
8462
The same writing in on the inner surface of the silver handle of the cup. The mark resembles Lenox logo but little different. The logo is like two wheat spikes and up-right sword between them.
