One of the keys dates for the later Liberty Head Nickels . AG3 I would say, but still worth a few bucks.
Sorry, but not really in this condition. The 1912-D nickel begins to become a better date in VF and better. The pieces in Good sell for common date money. The Mint State coins are really tough, like the 1912-S. A quick historical note - the Denver mint started making nickels in February 1912. The San Francisco Mint coins were all during the last week of the year.
I think it looks like a slight MAD but it could be the wear causing it. I think it’s in good condition. A semi-key date with nice honest wear. Congratulations.
