The problem is , you would have to know what to collect. Lol. Lenox and stuff that were the poor persons china, is almost worthless. Found everywhere for 5 bucks. Waterford, while higher class is still not a great resell value. If your collections are worth it , go for it. But for some, the idea and hasstle of selling stuff to make a few hundred isnt worth it. To emphasize the point, when my aunt passed we had a lot of high end knick nacks, one of a kind signed things, Tiffany paperweight, stangle, etc. I tried selling them in a house sale. No one wanted them. I packed them up and put them on a 5 doller table at a garage sale. Even told the people anything for 5 bucks , some of it is worth 100 bucks or more resale. Not one of the high end items sold.
