The product is a vintage Tiffany & Co. money clip made of sterling silver, with a striped pattern and the Tiffany & Co. logo accent. It  was given to me in the 1990s and was vintage when I got it. 

I am told the patern is called engine stamping.

if you look closley it appears that at some point it may have been engraved, there are 4 'dots' in the engraving area.

I used silver dip to clean the clip for these phtots but I bet some actual siver polish this woud really shine although I like the clean patina it presents with as pictured.
