This is a political note celebrating the fall of a government. The date overprinted "7 February 1986" on the note was the day the Duvalier Government (President Jean-Claude Duvalier) was overthrown by a popular uprising in Haiti. It is also the day that Jean-Claude Duvalier and his family accepted assistance from the US government and flee the country for France. I do not believe that the buster overprint on the note was sanctioned by the Central Bank of The Republic of Haiti. It is also believed that the overprint was done in the United States mainly by Haitian exiles opposed to the Papa Doc's regime. One may even argued that this is more like a souvenir note rather than a political one. I am not sure as to how many pieces were printed but whatever figures you read, these are just speculation only. One thing for sure is that the number printed is in excess of few hundred pieces, maybe more or maybe less. I am not surprised if they are still making this overprint, after all it's now getting popular among collectors and the artist may want to cash in more. I got this before it became popular and I am sure mine came from the initial first print run LOL! I bought this note from a local dealer purely out of curiosity. Most of the overprints sighted are on the 'S' prefix notes only.
My opinion. Unless you really want one, the current ridiculous price is asking for is not worth it.
This note is also known as the "Buster note", or even a note with "No parking sign on it".
