I had lots of trophies from running races that I acquired through the years. So I took off the metal plate that has the age group and race info on the front to save and gave the trophy to an organization that serves special needs kids. They have events for the kids and love to be able to give them a trophy.
With money so tight these days, might as well see if someone can put these to good use and have some fun. Maybe your local school would want them, also. I know that they are not cheap these days. They can make their own label or have some nice ones made without having to buy the whole thing.
