The only place I'm seeing a remote chance at split serifs is on your image of the T in Liberty (bottom left corner), maybe on the R image as well, maybe maybe on the I. Is that where you're seeing doubling?
Can you take better pictures of the I and T in Liberty? I'm in agreement with @Hommer and apparently in the minority but it looks like it could actually be an example of FS-25-1976D-102.
I see what OP is talking about, but I believe the steps on the numbers in "976" indicates machine doubling.
A coin can be a true doubled die and still have areas where it exhibits machine doubling as well. There looks to be separation with notching of the I, T and Y in Liberty but imo better pictures are needed.
Geeze @Rare-Tim, you're hurting my eyes with all that! Listen up, find out just how die doubling looks on a coin. It doesn't present in every which way. Then you won't see all doubling as die doubling.
Have you compared the mintmark positions? I haven't, but this may, depending on the location/postion, be enough to remove the possibility the OP coin is of this variety. Just a respectful thought....
Well, there are diagnostics for the FS-102. One being die gauges on the obverse and reverse. Known coin: OP's coin: Known coin: OP's coin:
These diagnostics, "A SW/NE die scratch can be found in the field below the RU of TRUST. Reverse: A die scratch runs NNE from the star below the A in STATES", are listed by Wexler, here http://doubleddie.com/1829488.html
