I've won my share of medals and I appreciate them when I do pull out a win or place in the top three.
They're nice to have for fond memories of one's shooting days, and if you get your name and the score engraved on them (as most are already stamped with the, date, placement, & match), your kids can enjoy (I think) and understand better what this shooting sport ment to you after you're gone.
I may never win another medal in my lifetime, but I do appreciate the opportunity to take away some token of achievement from a sanctioned match for the reason's I wrote above.
