I once purchased the contents of an apartment of a deceased individual, after the heirs had taken what they had wanted. I hired help to get things moved and spent most of the day, packing boxes and emptying drawers. All of the time I never paid any attention to a large pile of garbage in one end of the kitchen that the heirs had piled up with old clothes, canned goods, etc. It wasn't until I had finished and sat down in a chair near the pile that I noticed there were dozens of similar sized small cardboard boxes mixed in with everything else. Curious, I picked up one box and saw that it was sent from the U.S. Mint. After opening it, and finding a Proof Set of U.S. coins, I looked at other boxes...and each one contained a Mint or Proof set of coins. Hundreds of dollars in coins, headed to the landfill.
When one of the heirs arrived to lock up the apartment I showed him what they were throwing away. I think I made a new friend that day!
