Expensive Stops

 An elderly Romanian woman was using a 7.7 pound chunk of amber valued at $1 million as a doorstop. After the woman's death in 1991 a relative noticed the doorstop and thought it might be valuable. He sold the 38-70 million year old nugget to the Romanian state where it now resides in a museum as the world's largest intact piece of amber. A similar case in Michigan where a man had found what he thought was a rock on a farm and used it as a doorstop for 30 years before finally taking it to the Central Michigan University where upon examination it was discovered to be a 22 pound meteorite. The moral of the stories is watch what you stop?
