I have one of these uncirculated that I've had in a 2x2 since '01 or '02 and no idea where I even acquired it-question is I never heard of the 'experimental runes' coins till this week and it's awfully brown toned and way different looking than my '01 sac 1$ were any of these coins in general circulation? I can post pics when I get home if that helps at all thanks!
