18 k gold 950 platinum wedding band

[ghettosamson]

I found a really nice wedding band. I would like to know if there is a way to find out The makers of this ring. Also, what is the F4 engraving mean? Here is a link to pictures. https://skydrive.live.com/redir?resid=43919C935E2D9F41!10364&authkey=!AI7NBCu4QkOIwHk Also, should I get this ring appraised and sell it on eBay? I've read a couple of posts of people sending it to the refinery place but I would like to weigh my options. Thanks everybody for your advice.

Looks like a saleable ring...get an opinion or two about the metal content...rings of this style are known for not being karat gold.....

That mark is Frederick Goldman...they make their G kinda funny, everyone always thinks its a 4.
