UPDATE: will look to appraise my cob this weekend. And Swoly, I missed your post the first time. Thanks for the correction: ColOmbia. My gold cob brings all the numismaticists to the yard!
We expect a full report, B-Bob. Rest assured that none of us know where you live, or what you look like. (I would guess you look like Abe Lincoln, but that's just me!)
Royal Coin & Jewelry. They're on Beechnut just inside the loop across the street from Lowes. Free appraisals. They're good people. http://www.royalcoins.com/
Go to Houston Neumesmatic (sic?) Exchange in Rice Village on Times. They specialize in old coins and gold/silver buying and selling.
I sold a gold coin last week...1998 $50 American Eagle, 1 oz. After calling around, it seems places give you anywhere from 5% to 10% under the current value of gold ($1791/oz right this moment). Jumped $100 since I did it last Friday. DAMNIT!
