Which country has your coin designs?

My personal favorites are Austria and Panama.

Are you asking about favourite coin designs?

If so I've never seen a Moroccan coin I didn't like. I even got my first one recently.  :D Love Moroccan coins.

But honestly if I've seen a coin from a country I've seen at least one from that country I've liked. I can't think of a country that has universally ugly coins.

Panama, early to mid 1900s Italian and Vatican City coins

Italian. all the way

Loruca

France's 1899-1920 coins, from the centime to the 20 francs.
Also those Italian commemoratives of Victor Emmanuele the IIIrd are fabulous to behold.

Canada, Azerbaijan, and perhaps Serbia and Lithuania are the only ones I can think of where (nearly) all the (circulating) types are beautiful. (That and a few French colonies whose coins were all designed by Bazor.) My favorite coin type series is the current Armenian one, but the older (pre-2000) Armenian coins are a lot less pretty.

But generally, I have to agree with MonaSeaclaid: can't think of a country whose coins are all ugly. (Though there was a coin in my collection that I almost wanted to give away because it was so ugly... and it was from Panama. But most of their coins are a lot prettier.)

Early 1900's to 1940's Albania, Italy, and France and her colonies. Some of the south American republics around the same time as well
The British colonies had some very nice designs, too, overall.
