Like many here, I don't consider my own run-of-the mill medals particularly important. However don't forget that just as the medals of our ancestors (whilst usually having little monetary value) are of great value as a link to the history of our families, so our own medals will one day have the same importance to future generations. You'd probably never dream of boring your family with your exploits, but maybe think about putting a few lines about what job you did to earn them in that old box with your medals.
