"Under 18" (14 years old)
And my favorite coin is that quarter eagle. I too am starting a quarter eagle collection, in AU55 or better, and I own 1910 (AU55) and 1911 (AU58) (Both are in my $2.5 Indian album here at cointalk)
I think your coins looks very nice, and the marks, and hits match up to that of MY AU55, and reminds me of my own coin, except it is a different date of course!

Your coin is a very nice one, in fact, all of them are, and I am glad you took the time to join cointalk, and also show us your set.

If I had to pick a second favorite, it would definitely be that liberty nickel! WOW A MS66! That is a real nice one, very clean fields, and just an attractive coin overall!
Really I have to say that I like um' all!
Thanks For The Contest, and Thanks For Showing Us Your Coins!
