Hi all.
I'm not sure if this is American or not. Tried to research the "C 547" because I can't make out the mark above the word Sterling. I think the mirror is around 100 years old but could be off some. Thanks much for your help!

Hi - welcome to the forums. Looks like a Simpson, Hall, Miller & Co./International Silver knight's-head mark - by design, probably dates to the 1910s-'20s...
