I'm just kicking the can around some, no argument intended
POST-OFFICE, NEW-YORK, Oct. 10, 1862.
"Postage stamps" cannot be used as currency without diverting them from the purpose for which they were designed, and violating the orders of the Post-office Department. To use them as such is to wrest them from their proper office, and apply them to a purpose for which they were not designed. or adapted.
The Department, foreseeing the evil consequences which would result from this course, gave immediate and full notice, that it did not and could not furnish stamps for currency, and would only sell them to be used in prepayment of postage.
so are the stamps to add value to otherwise useless paper?
