Gold is over $100. Depends on what someone wants to pay. Dealers will try to buy 60 to 70% of value. Try ebay
Depends on the condition of the coins. The best advice I have is to just take them in to the fine people at Americana. They are honest, and give the best offers if you are selling, but will gladly simply appraise even if your not. Another option, go to NGC website, which is ngccoin.com and do an extensive search there to find the value.
Exactly as the first answer, take them in, superb people at Americana. Or, NGC website is also a good way to find values.
