Silver Over Copper Marked Vase

Neat vase I picked up at an estate sale. 12" tall and has a grape motif. The edges have copper showing thru. Not familiar with the mark on bottom.

 

Thanks I need!

 

The holes on the bottom (look like they're for screws?) bother me. I sincerely doubt that this is Sheffield Plate. If it was SP that was wearing, you wouldn't just see the copper layer appearing at the corners. The silver layer would be more likely to be detaching from the copper layer. And SP makers did not ordinarily use multiple "devices" in their marks.

I did find a single "unknown maker" example with the heart shape mark, but not the others with it.

 

Thanks I Need. I did see those when I was searching. This might be a tough one.

 

Alright - This is one is by Lawrence B. Smith of Boston. Nothing at all to do with Sheffield Plate. and other by Revere (not Paul!) Silver, also of Boston and both 20th century. Why these sellers are implying that they were either Sheffield Plate or made made in Sheffield England is beyond me. I'm afraid you're stuck with "unknown maker" likely US, 20th century, silver plated.

 

Thanks you Bakersgma!
