Hi there Amy - the common brands (White Horse, J&B, Ballantine's, Seagrams, Chivas, etc.) aren't going to hold much worth since they are still being produced and widely available today. If you have anything that was a limited supply or no longer being produced, from a closed distillery or pre-prohibition, there could be value. Try contacting a company such as McTears (
www.mctears.com) or Bonham's (
www.bonhams.com) with a complete list of your inventory. Both of these companies specialize in valuations. Good luck!
