The listing, 10k gold tie pin *please read description* has ended.
measurements are 1/2" x 3/8" x 1/16" (very small)
please take a close look at all the pictures,
looks to me like 10k stamped into the back
i don't know anything about tie pins or this logo on there... but if you have questions please ask...... if i can't answer them don't worry, our fellow Listians on here are quite smart and are more than welcome to chime in with their answers!
this is the second and last one I'm listing, thanks to the great listians on here commenting my last listing, i now have some more information on this pin=
the stamped 1/10 10k means total weight of idem is 9 parts solid nonferrous metal (like brass or copper) to one part gold 10k.... in other words heavily plated
