I like MrBAU's and iawgoM's designs best, especially their silver entries. I think MRBAU's silver entry would be a great choice for the gold coin.
I guess I'll put in my "official" vote:
Gold: #14 by MrBAU (but I also really like Silver #14 by MrBAU)
Silver: #3 by iawgoM
Two thoughts:
1) I think Coinographic should use the community votes as a guideline only, and make an executive decision on the final winners, even if they don't get the most votes.
2) My actual vote would be for silver to be iawgoM #3 (as voted), but the gold coin to use MrBAU's Silver #14 "Raptor" design, but I don't know if that's a valid vote.

Great competition!
EDIT: For the "Raptor" design, I recommend turning the "," to a "." because the period is a more universal symbol for the decimal symbol.
