I got this and some others @ an estate sale & have no idea how much it is worth. Any help would be appreciated. It is 31" tall & 11" across at the bottom. It has a removable stopper in the top.
Then I think your best bet is a local consignment shop or antique dealer. I don't know of any other good way to get an appraisal (unless Antiques Roadshow happens to be in town).
I didn't realize they charged, but it makes sense. I guess if you are sure you have two other items that are worth quite a bit, it's worthwhile to take your stuff.
You could also try taking it to a consignment shop and see what they tell you.
