What is the value of an 1831 US silver dollar?

Please check again and post a new question. There were no US silver dollars minted for circulation from 1804 to 1835 inclusive.

If the coin in fact has that date and denomination, it's counterfeit. The market has been flooded with fake dollar coins. Some of them are laughably bad, with impossible dates and/or designs although many others require an expert to identify as fake.
