Here is an interest bearing note that was issued by The Bank of the United States dated December 15, 1840. The note features a picture of the bank’s head office in Philadelphia. On the reverse of the note, there are stamps indicating that the interest was paid on this note until October 1, 1850. If the bank was liquidated in 1841, how can this be? Who was paying the interest? I have not been able to find an answer to this question. I would appreciate it if any of you could explain this. Thanks! BTW This note is PNG certified as an AU-55 EPQ.
