Late to the party. It's another beauty! MS-63 seems spot on.
My knowledge of the 1878 is deeper, because I had a client who was trying to assemble a complete set of 1878-dated coins by variety. (Yes, he picked THAT year.)
I know there are three pitted die varieties in 1875, with some debate between acid-treated dies and simply rusted dies. This has to be either F-103 or F-109. I can't get a clear enough view from the pics, but the degree of pitting on the shield doesn't seem as severe as the almost completely missing left half of LIBERTY on the F-103. To me, the die cracks on the obverse are light, but look more like the F-109. The missing central serifs on DIME sure look like the 109, as well.
Again, absolutely fantastic coin.
