weird state of missouri note 1 1

[Roy Winters]

ok there are two things that weird me out about this bill.  first of all it is an 1862 bill but someone put a 4 over the two?  also on the back of it, it appears to be a louisanna state bill partial print.  I am going to assume it was stacked on top of the lousianna bill and just got transferred to the back.  I am going to submit it but was curious what you all thought?

here is a close up of the date.

Don't know much about this bill but the last two that sold at auction on ebay went for under $80 each, this note is in much better condition than those so I'd estimate the value at around $150.  The 4 over the 2 and being printed on the back of another note or used sheet is normal.
