Sometimes local antiques dealers also do appraisals. You could call around to local shops and see who does it. I know here there is a man who does it and I beleive he charges about $10 per item.
Another option is to take a picture and send it to one of the larger auction houses. Again, this isn't a free service. We had it done years ago and paid $50 for the appraisal for one item.
As far as selling your items goes, its really a down market for antiques/collectibles. Like anything else when the economy is bad things either don't sell, or don't get the prices they used to. I used to sell a lot of antiques/collectibles on ebay but stopped as stuff just isn't selling and what is selling is going really low. I have inventory but am just waiting it out. If you go with someone local for your appraisal they might know of a collector that's interested in your items.
