Any 1840 $1,000 Bank of the United States note with the serial number 8894 is a replica that was made in the 1960's for a promotional giveaway in cereal boxes. These replicas are essentially worthless. These replicas are made from yellowish-brown "antiqued" paper that is crisp and brittle to the touch. The genuine $1,000 Bank of the United States notes are printed on thin banknote paper that was originally white or cream colored. One supposes that if a genuine note with the serial number 8894 ever were to show up that it is likely to cause quite a stir among dealers and collectors who have grown weary of answering questions regarding this particular replica.
