The 1915-S is a key date amongst the $10 Indian Head gold series. In fact, all S-mint issues from 1911-1916 are exceptionally scarce and carry a premium, especially in mint state. Now, this 15-S is only AU58, but the 1915-S has the 2nd lowest mint state population with the 1911-S being the smallest. Given the rarity of the 15-S, I actually think this coin is undervalued. For the coin itself, the color and luster is strong and it has shine and great eye appeal.
