All-
One more error coin for the night (the excitement is killing me!). I didn't see any true doubled-dies listed for this year at coppercoins (though the site appears to be wonky at the moment), which makes me think
Machine Doubling. Interesting how it hits certain parts of the design and not others...
The obverse is unremarkable (again, 1981 from Philly)- here's the whole reverse:

Here you can see the doubling of some of the letters, particularly the "TES" of STATES, the "o" of OF and the "AM" of AMERICA.

And lastly, there is doubling down most of the right side of the edifice. The "FG" shows no sign of doubling.

Am I (finally) right on this one? It would be my first
Machine Doubling find!
cheers,
