The book I own is titled,
A Register of Liberty Seated half dollar Varieties Volume I San Francisco Branch Mint by Bill Bugert.
I am leaning towards it being a Micro S.
The above book has the necessary info to help you determine which die pair it came from. There are 10 die pairs for the Micro S, all but one are R-3 or R-4.
However, this book
does not mention values.
If you want to purchase a copy, Rich Urich has some for sale on his site. That is where I acquired my copy from.
