14k tiffany & co Mechanical Pencil

this is a tiffany mechanical pencil that I believe is from the 1930's. there is no markings on it other than the tiffany & co and the 14k gold stamp. the pencil is opened by pulling the ends and the led is lengthened by twisting the lead holder. there is little detail on teh web for this particuliar item. It is a bit tight to open but other than that looks very good shape. I am unsure atthis time whether to sell. I know the price is I sold for gold scrap but with tiffany it may be worth more. I just dont know how much more
