It's a soft strike, most evident on the obverse. The second cotton blossom, cap, cap fold, big bear claw, lower ear lobe, and hair above the ear are weak. The reverse weakness is more subtle, but is evident on the talons, legs, and ribbon. IMHO, this earns a half point deduction if the coin is uncirculated.
There is just a little too much glare in the obverse photos to be confident of a grade. There could be a touch of wear on the hair and on the eagle's breast, but if not, the contact marks make this coin a 62. On the obverse, the contact marks over the eye, in the visual center of the cheek,and between the cap and the UM of UNUM are consistent with a 62. The reverse is better, but the field contacts above the motto cap the reverse at a 63. Because of the strike, the blended grade would be a 62, again, if there is no wear.
You have the coin in hand and can distinguish between strike weakness and wear by looking at the luster on the weak points. If the luster matches the surface in protected areas, what we are seeing is just strike weakness, If the weak areas show less luster, then there is a hint of circulation, and the coin would easily straight grade as a 58.
It's a nice coin, and 1889-S is still a bit of a tough date, despite the bags discovered in the great silver rush of the 1950s and 1960s.
