I saw several of these stamp cancelled notes on Ebay- the top one in a Buy-it-Now listing for $500 OBO, this one in a Buy-it-Now listing for $125 OBO, this one for $100 Buy-it-Now OBO and lastly this one for $95 Buy-it-Now OBO. Each one is from a different seller. Is there something special about sticking old stamps onto a $2 note, and getting a modern cancellation stamp (from 2013, 2015, 2019, etc.)? Or tacking on new stamps, and getting those same modern cancellation markings? I understand the "First Day of Issue" stamp cancels for 2 dollar notes from 1976, but what's so amazing about these notes? It seems that if a stamp itself is rare, it would make more sense to auction the stamp, or the stamp with the envelope it was affixed to. The modern cancellation markings make even less sense- I could literally go to the post office, and have all the money in my wallet stamp cancelled (04-20-2020). This bill sold at auction for 16.33 (including shipping). But what's so epic about it? The forever stamp at left is from 2018, and incredibly common today. As for the New Hampshire 3 cent stamp- it's worth approximately a dollar-uncancelled.
