A collection of twenty American silver certificated One Dollar bills. Series 1935, and 1957. Each is numbered and marked with a blue seal. Silver certificates are a type of representative money issued between 1878 and 1964 in the United States as part of its circulation of paper currency. They were produced in response to silver agitation by citizens who were angered by the Fourth Coinage Act, which had effectively placed the United States on a gold standard. The certificates were initially redeemable for their face value of silver dollar coins and later in raw silver bullion. American Paper Money, Currency For Collectors.
