Should I consider cleaning up and selling? If not I'll be donating everything in mass.

I'm posting this question all over, but essentially I'm moving out and have a ton of LEGO friends, elves, and whatnot that my mom's just gonna throw away or donate if I can't find any worth. Some of my stuff are from the 2010s while some others might be from before that, but gonna be honest I've got no clue as to what's super hot in the markets today. I briefly sorted, but I dont have any of the old instructions and lots of it is all mixed up with how elementary school me imagined and played...
