My mum, who worked at a hotel in France in the 80s, was given these by an antiques dealer as a tip for caring for his mother during their stay. They've been kept in a paper envelope since.

Supposedly these are Assignat, issued by the French government during the French Revolution through a tumultuous period of economic chaos and inflation caused by the overprinting of paper money such as this, among other things. These are at the value of 50 sol (50 cents).

I doubt they are worth very much and they are not in great condition.
