Hi, I have these coins pictured from my grandfather as well as some silver…

They sure are, Suzanne! As a quick rule of thumb, you should get at least $100 per face value of pre-1933 U.S. gold. So a $5 gold piece from the late 1800s or early 1900s would be worth $500, and those big, heavy ol' double eagles, which are marked $20, would get you $2,000. And we often pay more, depending upon the date/mint combination, condition, and current market. Why don't you call us at 649-3317 (area code 914) to schedule a visit for a proper appraisal in our lower Westchester office? We also assist with selling, either via direct offer to you, consignment/referral, or auction. --Marc
