Bravo, TG! What an analysis! Though I don't agree with every point, I love how insightful you are!
1) I think the gov't already has done that research under more... enlightened congresses. Might only take the signature on a law to get those coins minted. Maybe switching out machines and suppliers would take a year, but the research should be done.
2) Liberty would be great but there's too much financial interest in more tangible designs. I wonder how much each parks' tourist numbers have improved
3) dead on
4) never liked holed...
5) great point I never thought about!
6) keep it as is.
7) not gonna touch this one!
