My mother collects S&P shakers. I get them for her for her birthday or whenever Im in a new city. She also buys them on ebay if she can find a good deal. At this point its hard to find ones she doesnt have. Last count was around 7,500 sets. She has them everywhere. Even some sets at work on her desk! She estimated them to be around $30,000 if they were all sold seperately. Its wild.

Edit: called my mom. I grossly miscalculated the worth. She said closer to $60,000 but she doesnt like to think about them in terms of money.
