There are many very similar doubled dies in this series-most are Class IV (offset hub doubling, see Wexler http://doubleddie.com/ for an excellent explanation.) Most of these show only a small area of doubling, on the reverse it usually involves the part of the EPU motto toward the "interior" of the coin-"E" "PLU" and on some of the Bison's fur details. The well known 1930 "five legged buffalo" is a somewhat atypical example of this form of doubling.
First year out too .. I sure the mints were looking for high volume for the first year, out of mints too ......
The Mint had a lot of trouble with this coin until 1916. Dies were only lasting for 50,000-100,000 coins.
If you want a detailed read of this problem see "The Renaissance of American Coinage-1909-1915" by Roger Burdette. I highly recommend this and the two other renaissance volumes-they the best numismatic books I've ever read.
I bet, just look at the relief and design compared to it's predecessor the Liberty "V" Nickel. A lot more metal flow for a rather hard metal.
That high relief is one of the things I like most about the Buffs. They've actually been called "small medals." I believe they are the highest relief circulating coin ever minted in this country.
I have to agree with you. The Type 1 just draws me in. I love the full mound under the buffalo. I know why they recessed it, but to me it just takes away from the stellar design.
