We once heard a collector refer to these as "rare as hens teeth." While they may not be quite that rare, nice looking examples really are few and far between. You could buy a lot of things with $20 in the 1860s and 1870s. There was no incentive to hold a $20 bill just because you liked it. If you had one, then you spent it. These are not considered traditional rarities, but they are by all means rare. Contact us for value information. Don't forget to check the serial number. Number 1 notes always sell for nice premiums.
