These are rare and beautiful bank notes. At least 55 are known to exist today. That number usually creeps up by one or two examples every few years. So these are getting slightly more common as time passes. However, they will always be relatively rare. Very few banks issued such a high denomination during this time period. Values start at around $10,000 and go up quickly from there. Contact us for details. Don't forget to check the serial number. Number 1 notes always sell for nice premiums.
