Spokane Stock Exchange

The Spokane Stock Exchange was a regional stock exchange in the northwest United States, located in Spokane, Washington. Founded mainly to trade stock of mining companies, it began operations in 1897 and closed 94 years later on May 24, 1991.

At the time of its closure it had a reputation as a haven for trading speculative penny stocks, almost exclusively in mining metals stocks of the Silver Valley in nearby north Idaho.
