Yes, those are some nice coins..however not as attractive as bimetallic coins.

I have some 8 or 10 (monometallic) of them, I miss the recent issues..One good thing about these monometallic issues is that there aren't mint varieties if I'm not wrong (I collect these R10 commemorative coins by mint mark

)..So easy to keep a track of what we have and what we don't have!
I'm still missing some (have got 94 or so) of the bimetallic R10 coins (three of them are very expensive, rest should be easy)..
