I was lucky enough to receive the first bitcoin transaction, and then I was careless enough to spend it accidentally. I probably still have the key sitting on a switched-off computer, so I could auction off the key. Usual caveats about making sure I delete it when I sell it...
It seems even the legend himself understood that the first Bitcoin involved in a transaction held historical value!
I've recently made a post about rare sats. I hope you'll find it interesting:
