You can look up "Coin Brokers or Dealers" in your local Yellow Pages. Many antiques dealers, fine jewelers or fine collectibles businesses have coin appraisers that work with them.
Even though your coins may be old, it is the QUALITY, YEAR and the minting location that determine their true values! The more "pristine" a coin is (sharp design, no/few scratches/wear marks, etc.), the higher the value. You'd be surprised that a coin that has survived 60-100+ years may not be as valuable as you think because of it's condition!
