What is the value of an 1877 us dollar coin?

Answer 1

There were no standard silver dollars minted that year. If the coin's date is in fact 1877 it could be one of the following:

> A "Trade dollar" minted for use in international commerce. Trade dollars have that phrase on the back of the coin. If it has a "CC" mint mark it's worth around $500; any other mint mark (or none at all) is worth about $90.

> It's a counterfeit. There has been a flood of fakes over the last few decades, some very good and many others with "impossible" dates or designs that stand out as forgeries.

Either way, you'll need to have your coin evaluated in person by a dealer who is experienced in 19th-century U.S. coins.
