All nice. The second note looks like the corner was cut off and it looks like the serial number is 3553, a radar.
Mea culpa, this is not a banknote or scrip, but a plain old Christmas card cover reminding me of my youth in the North snow country at Christmas and watching the trains go by our house; waving at the engineer and hearing the loud whistle.
Did someone mention trains? This is a CSA Note, $100.00. The serial number is 59,000 and there are 2 interest stamps on the reverse along with a signature. It’s dated October 13, 1862.
