B.U. or Beware
Several years ago Donn Pearlman wrote an article entitled, B.U. or Beware, published by the Chicago Coin Club. He discusses collecting coins as an investment rather than a hobby, and outlines two horror stories.
It’s worth a read if you’re interested in becoming a coin collector, and gives you a chance to evaluate why you’re becoming involved. If you’re doing it because you find it interesting and fun, by all means do so. If you’re doing it to make a quick buck, read the article a few times and see how you feel about it then.
