FDR was an avid stamp collector. Did he not receive some rare and valuable error-printings? I thought I recalled some controversy about it.
Reminds me of the gun that killed Jack Ruby... it was slated for destruction at one point, seized as an unregistered firearm. I don't know how that case turned out.
Just tossing this around. I think "uncirculated" has to be defined better. I believe there are plenty of "uncirculated" coins in the hands of the Public. I think it just depends what door they go out of.
