Obverse Dies: 21 Known
1875 Philadelphia dimes are common in all grades including Mint State. It is expected that additional date position varieties will continue to surface as I have not made a priority of researching 1875 die varieties.
Plate Coin: F-124, Well struck gem example with golden obverse and reverse centers that transition to peripheral rose, blues and green tones.
In 1875, most U.S. silver coins returned to "normal" -- that is, the arrowheads that appeared in 1873 and 1874 were no longer used to differentiate the new coins from the old.
Dime production at the Philadelphia Mint in 1875 was impressive -- over ten million Dimes were struck and placed into circulation. As a result, this date is common in most grades, up to (and inlcuding) MS66. In MS-66+ and MS67, this date becomes extremely rare, with only a handful of coins at this level.
Strike quality for this date can be inconsistent, perhaps due to the large mintage. Some 1875 Dimes are well struck and lustrous, others are softly struck, especially on the high points of the wreath. Still others have a grainy appearance from being struck using old. worn-out dies.
