A “Louisiana routing number chase” is a highly sought-after numismatic collectible that consists of a one-dollar bill bearing a routing number from the Federal Reserve Bank of Louisiana. These notes are exceedingly rare, with only a few known examples in existence. One such note, bearing the routing number 610916192, was discovered in a small-town bank in Louisiana in 2005.
These routing numbers were mistakenly printed on a small number of one-dollar bills in 1969 due to a printing error. The routing number 610916192, specifically, was intended for use on checks drawn on the Federal Reserve Bank of Atlanta, not on currency. The extreme rarity of these notes has made them highly valuable to collectors.
