I enjoy the reverse designs on the series 1914 $5, $10 and $20 Federal Reserve Notes (in case you couldn't tell from my avatar. Gotta love locomotives!). These designs in particular seem to work very well together ... the $5 depicting the "discovery" of the western hemisphere by Columbus and the landing of the Pilgrims, the $10 agriculture and industry, and the $20 picturing "planes, trains and automobiles."
America, boasting about all of the things she was most proud of at the time.
The "Panama" design on the 1914 $50 is lovely as well, but doesn't work as well with the smaller denomination notes IMO.
And the $100 ... again, a nice design, but more akin to something from the age of the "educational" notes. These allegorical designs were most likely lost on the general populous who would have traded them. Of course, I guess there were few common-folks who ever got there hands on a C-note in those days ...
And as far as your Second Amendment proposition ... The Pioneer on the 1907 Woodchopper Note seems awfully proud of his his axe, but his long gun is easily within reach behind him if the need arises.
