This really is a tough call, but I have to go with Zino's design for originality of design. There are several things  I would tweak on it though.

1- as mentioned before, change the playful font
2- the "electricity" symbol could be less.... harry potter? lol.
3- I dislike the leafy strands on the exterior edges. too traditional. I think it should be just left blank, or have some kind of "technologic" feel to it. The coin is already pretty busy as it is.


Hope this helps!
