France has come up with 4 versions of commemorative coins issued in celebration of International Year of Astronomy 2009. In fact France has the most valuable of all the IYA2009 numismatic collection, which is a graceful golden coin, valued at $2,000. This French IYA2009 coin, issued by the Paris Mint is the first domed coin of IYA collection, having convex (slightly bent upward in center , just like a lens) and concave surfaces on obverse & reverse sides respectively.

There are also the face value of 10 Euros, denomination, mint, the Year of 2009 plus an inscription in French meaning the "40th anniversary to the first landing in Moon", lie in the obverse.
The reverse appears quite simple, resembling a planetarium like insight. It appears as such that the dome of the sky, complete with the stars all over the reverse. The Saturn is highlighted there in the top with much bigger print. The lower edge is made creative with the astronomical symbolic forms of planets, starting with closest Moon and going through all the way to Pluto. Yes Pluto is there but not in its standard symbol (♇). It's also noteworthy that Earth is missing in the queue.
