Q: I have several license tags, including a rare porcelain plate from Iowa, a 1921 Colorado tag, and about a dozen from various states that were issued during the 1930s. I would like to contact others who share my hobby, since I have several duplicates. -- Carl, Grand Junction, Colo.
A: Some sources that might be helpful are Dave Lincoln, a collector, P.O. Box 331, Yorklyn, DE 19736; the Automobile License Plate Collectors Association, P.O. Box 7, Homer, WV 36372; and The Plate Trader, an excellent newsletter, 21 Ridge Run SE, Apt. D, Marietta, GA 30067.

Q: I have a bottle of Kennedy Scotch Whisky imported from Scotland. How much do you think it is worth? -- Claire, Nashua, N.H.
A: Since I have no idea of when your whisky was distilled and if it has any historic value, I can't answer your question. Mike Strother is a collector who is especially interested in tax stamps, labels, documents and other items relating to the distilling industry. He might be able to help you. His address is 4677 Spring Creek Drive, Lexington, KY 40515.

Q: I have an old lawn mower that has been owned by my family since the 1930s. Is it valuable, or should I toss it? -- Steve, Albuquerque, N.M.
A: I'll cut to the chase. Most of the older lawn mowers manufactured in the United States have very little value. In my 30 years of writing this column, I have yet to find a club for collectors. I suggest you post it on eBay, and if a feeding frenzy develops, you'll have your answer.
