My mother has some base edition cards she’s wanting to sell what’s the best route?

My mother has a stack of what I believe are base edition cards from the third print run and some cards from the fossil set.

I'm personally a magic player so I know a handful about these types of things, but I have no idea how to go about selling these. Tcgplayer would be the initial thought process but that's a lot of work that we just aren't interested in doing, would going to a trade show be the ideal way to do it?

She has the entire card list from both of the sets.

Any help would be immensely appreciated,
Thanks in advance!
