I would say that it's worth keeping them. If you regret selling a game then the experience just can't be matched with emulators.
There is an important upside with emulating though: The batteries of old cartridges dies after approximately 20 years (if my memory serves me right). Meaning that you can't save your progress anymore, and that all of your old saved files will be deleted.
A bonus is that you can play some old games online with the right emulators (like I do with my Nintendo 64 games), but I guess I'm going way off-topic now :)
