Anything? Depending on the value, I'm either going to put them on the Bay or give them to my dad for his birthday tomorrow.
My book only covers the 20th century, so I can only weigh in on the 1916 10 centime. I see those occasionally in junk bins for about 10-25 cents each, but when I do, I pick them out. In the book, it's listed as a relatively high mintage: 22,477,000. In F to VF, it's $0.25 to $0.75. If your dad's a collector or if France has some special value to him, then they sound like really fun gifts. Who knows? There may be a key date in the batch.
Thats my favorite one. What does it go for in MS or AU? Dad was born in 43 so I'll probably give him a MS63 43 merc w FSB since it is a duplicate.
My 15 year old Krause book lists it at $7 in MS (the 1916 dix centime, that is). I suspect it would go for closer to $20 in a slab, which still seems hardly worth it and a good deal. Those are beautiful coins, IMO.
