I doubt it was paid for with American money.

Like you, I'm also pretty sure it wasn't paid for with American money.   (That post was just meant as a joke to the person who wanted that rare old stamp -- my post shows a front and back picture of a very rare "1909 S-VDB" U.S. penny, which would be worth a lot of money to coin collectors today.   For all we know, that 1-penny stamp might have been paid for with two old British "half-pennies", but I don't know which of those would be highly valued by today's "numismatists".)
