Does anyone own any collectable ornaments that have increased in value over the years?

In 1979,a friend gave me the very 1st ornament in the Frosty Friends series by Hallmark. This year is it's 31st year. It probably cost $5.00 at the time. I was looking online a few days ago and came across a site which was selling old ornaments. It's value, in perfect condition (which mine is), is now $495.00!!! Nice return on investment!
