Thank you to anyone who cares to share some wisdom. I have some antique pitch filled candlesticks (~585 grams, 9.5" tall) here. I could use some help with them. Can anyone give some insight as to the date of these, whether these are in fact sterling, and where they may have been made (I believe American)? General form is square base with oval fluted columns. 14 sided removable cups.
These are machine engraved with a social security number that traces through the SSN Death Index to a wealthy Colorado owner who was born about 1918 (I bought these in Denver) and died in 2007. Simply stamped 'STERLING' and the number 90.
And in other places (removable cups):
STERLING OR STERLING
90 90
6 2
