Yes it is. Thought I'd try it based on the other thread asking about one (different) one. Thought I'd give it a try. I have all the other answers, and am stumped on these right now.
The boat is a 1930's 2 Zlote piece. 75% silver content. I believe the other are polish as well judging by the artwork, but I'm not sure.
Nope, the boat is actually Portugal I would very much like to know what coin is the second, in the center.
Last year I participated in a contest where you had to guess places/locations based on Google Earth images. The winner would get a TomTom. And all of a sudden there were posts in various (unrelated) forums about "hey, does anybody happen to know where this is?" Booo. That being said ... Liechtenstein 1946. Could be the 10 fr or the 20 fr piece. Christian
