I have #7. But it ain’t worth that much. I think last time I looked, my version was around $800.
Stamp collectors are the ultimate in picky. 99% of people could not tell the difference between my $500 stamp purchase, and a $300,000 stamp.
That’s why you have to get them certified.
Generally speaking…your “grand pa’s” stamp collection isn’t worth much. You aren’t finding these stamps in the attic. Lol.
I love the movie “Brewster’s Millions” starring Richard Pryor, where he used a Upside down Jenny stamp to mail a postcard!...............
I admit I don’t understand the attraction of US stamps although they are well made and durable, versus say a Queen Victoria Zululand overprint.
