Not quite what you're looking for, but Antartican currency has penguins on it! http://www.bankofantarctica.com/currentissues.php Also, 1991 Cook Islands 50 Dollars, 1998 Falkland Island penny, 2007 South Georgia & Sandwich Islands £2 silver dollar. I'm sure there are more!
Penguin....now THAT is a tough coin. I thought my animal was bad, a rhino on an ancient coin. I have a few, but they are all quadrans of Domitian, both left and right.
Here is a proof penguin piece currently for sale on Ebay. http://cgi.ebay.com/New-Zealand-198...732?pt=LH_DefaultDomain_0&hash=item4cf69ccd04
Weird, this is the same kind of penguin, same country, but a different coin as one listed above http://cgi.ebay.com/YELLOW-EYED-PEN...New-Zealand-2011-/370493293322#ht_2419wt_1139
Ah, you just need to be a little flexible: http://www.muenzauktion.com/aurich/item.php5?id=3709 Strictly speaking, the piece depicts the "Western Capercaillie". But ... Here is a gold coin from France (Int'l Polar Year) depicting two penguins: http://www.emuenzen.de/verkauf/10_Euro_Adelie_Land_inkl._Orig-21513.html Christian
I have one of the Andorra Capercaillie coins, a Capercaillie is not a turkey. Andorra 5 Centims 2002 Gall Fer (Capercaillie Grouse)
