Every once in a while, people find things that are old that they believe are worth money. Some of these things are valuable and sometimes they are not. It just depends on what the item is and how well it has survived over the years. I had a sewing machine from 1892 that I thought was very valuable. It turned out that it was not.
Other things like comic books and games can be very valuable especially if they are the right kind. Condition is always a concern but in the end there are many things worth money. The moral of the story is that you need to check the worth of an old item before you throw it out.
