Since it's a coin about virtual drug deals, I think you might be on the right track with the one where the two hands are swapping cash for a baggie.  Maybe swap the green out for a dark purple background in the inner circle behind the hands, for contrast.  Change the font and make it bigger so the name of the coin stands out more.  Lighten the rest of the green on the coin, darken the green in the name of the coin.  Again, for more contrast.

Wait for Ace_Of_Fades to come back and check them out though before you spend too much time on this.  Like I said, I haven't discussed the logo with him and am not sure if he had anything specific in mind.  Don't wanna make a unilateral decision here.
