Tough call from the images. Throwing the strike aside I'm thinking AU58 based on the reverse fields. If I'm wrong and it's MS I would say MS63. Hope I'm wrong.
This If i could see more luster in the image i might stick my neck out there @ms63, but i cant, so i wont. AU58
Thanks. Yes, the 1891 O and 1892 O can get a little pricey in MS. I consider them underdogs in the series.
