>dime - President F Roosevelt/liberty torch

Yeah, and the liberty torch is flanked by what look like two sprigs of parsley for garnish... one's got to be an olive branch, I guess I'll have to go the the US Mint website and check out the herbs.

>half dollar - President Kennedy/?

I just so happen to have one in my purse (didn't I mention I hoard odd currency?). JFK is indeed on the front, and the Presidential Seal eagle is on the back (shield in front, talons outstretched holding olive branch and arrows, 13 rays, blah blah blah). Looks like 50 stars around the eagle (to represent of each state), but I'm not going to count them just now.

And with regard to my pet, the two dollar bill (good for you for carrying one, Faldage!), I think one of the things that attracts me most to it is the phenomenal detail with which somebody's famous painting of the signing of the Declaration of Independence is rendered.

I promise when I get home I'll check my stashes of Ecuadorean sucres (a rare find anymore...), Korean won, and Chinese yuan. I'll report back when I know more, Cap'n.
