My deepest apologies to all! Sheesh! What a maroon. coin_nut is dead on; Luxembourg is not accessible from the Netherlands without winding up in another state.
We have languished here for over 48 hours, so I will post another Netherlands, 1906 2 1/2 cent "woody"
Without a doubt, Monaco is reachable from France. For your viewing pleasure, a 1956 Monaco 100-francs coin. Those Grimalidis, Ranier III being just a more recent Grimaldi, have kept that parcel of land for over 700 years! Talk about persistence!
