Q: I have a bunch of original McDonald's stir rods from years ago. How can I find out more about them, and where can I take them to sell?
A: Send a photocopy of the stirrers (which may be rare) to McDonald Collector, P.O. Box 83, Winnetka, Ill. 60093, enclosing a self-addressed stamped envelope for a reply or cash offer. It's said that the original McDonald coffee stirrers, with the original // Golden Arches at one end and a small spoon at the other, are extremely rare due to the fact that they were being used for drugs before the spoon design was replaced with a small flat paddle for stirring.
Q: We have a meteorite which measures about 2 feet long, 18 inches wide and 12 inches high. How can we find out if it has any value, and if so, who might be interested in buying it?
A: Meteorites are like "pennies from heaven," and to find out just how many pennies your specimen could be worth (rare forms of meteorites can be surprisingly valuable) write meteorite maven, collector and buyer Robert Haag, P.O. Box 27527, Tucson, Ariz. 85726 (phone  882-8804); enclose a dime-size piece of the specimen to be examined, along with a description and photo of the entire piece, and your name, address and phone number.
Send a self-addressed envelope with enough postage should you wish to have your sample returned.
You don't need a rock to fall on your head to learn how to recognize a genuine meteorite. According to Mr. Haag, many types exist -- rough, smooth, large and small. Look for rocks that are especially heavy, or with signs of melting or rust. A freshly fallen meteorite often has a thin black skin or "fusion crust." If you find a rock that attracts a magnet, it may be a meteorite. How can you tell? Mr. Haag explained that a strong magnet on a string will swing towards all meteorites, which makes this one of the best preliminary tests. Other excellent field tests for meteorites include checking rocks for rust, and filing off a tiny corner to look inside for bright metal or metal flakes.
