In 1936, the Alberta Social Credit Party-led government of the Province of Alberta, Canada, introduced prosperity certificates in an attempt to alleviate the effects of the Great Depression. Social Credit Premier William Aberhart's government had won power in the 1935 provincial election partly on the scheme.
Although not technically money, each certificate was intended to circulate with a value of one dollar. The intent of the program was to keep the certificates circulating and discourage hoarding. To achieve this, a holder had to affix to the back of a certificate a 1-cent stamp before the end of every week, for the certificate to maintain its validity. But the hassle and expense of the stamps made the certificates unpopular with the public. To make matters worse, the tiny stamps (smaller than 1 cm²) fell off. To avoid having to purchase and affix the stamps, holders would try to spend the certificates just before the week's validity expired. That left them in the hands of merchants, who would have to purchase and affix the stamps themselves to maintain the notes' validity.
The notes were intended to be redeemed after two years of issue, when 104 stamps would have been affixed. But the program was cancelled after only about one year.
