I like the chart behind #11, but I don't like the character.
#12, 13, 14 - The character is ok, but I'd like more detail to it. I like the tie idea, but maybe add the shoulders and collar of a suit just to flush out that idea a bit. The money looks too cartoony.
#14 I like the font.
Some examples of flushed out characters with detail:
