D'OH!
My guess is that this particular Jenny would collect a premium because of the circumstances of its discovery.
More than likely it will end up in a local museum and never end up on the market. Unless of course the local government is need of cash.
What do you bet that a whole host of fraudulent claims by people trying to cash in on this stamp.
I asked my kid to stamp my ballot in mail it. The kid mistakenly got in to my stamp collection and put my $200K Jenny on there. So can I pulleze have it back.
