You can purchase a pretty nice Security Six (200 yr Edition) on Gunbroker right now for $280 plus $20 freight. I'm trying to figure out what makes the bicentennial issue so special other than (I am assuming) it was made in 1976.

Gun was made in 1976 with a special marking. Don't think Rugers made that year have extra value because there were so many. $275-$325 depending on conditio n and where you live.
