If you have things that could be of a decent value check out the ValueMyStuff website. It's around 10 bucks per appraisal. I buy and sell a lot of antiques and the things that I don't know about, I go to them for, they've been pretty accurate so far. One thing they do tend to be off on is original Americana as most of the appraisers are British. They appraised a federal painted chair from 1780 for around 500 bucks, I sold it for 3k a week later. Art, jewelry, ceramics etc they have all been spot on with.
It's honestly going to depend on what it is you have to sell. Old Americana you can go to one of the big auction houses to consign, heavy stuff you can take a trip into a larger city and set up at a flea market, small stuff, ebay is still the way to go.
If you post some pictures I may be able to tell you what would be of value. The crocks, if they are bean pots, you'll have a hard time selling despite the prices you see online. If they are salt glazed stoneware you can probably sell them fairly easy. The more ornate the blue decorations on them the more expensive they are usually (barring damage of course).
Some of the hot things that are selling now, that I've seen a lot of competition for lately...Antique Halloween decorations, original americana (think painted boxes, chairs, chests, weathervanes, whirlygigs, signs etc), vintage recipe books with good graphics, high end costume jewelry, and vintage posters with good graphics.
