Years ago I bought some mercury dimes and stumbled onto a one with the bundle of sticks on the reverse side looking more detailed than the other silver dimes I purchased. Not sure if my smartphone did the best job of taking photos of it. But when I have the time I can take a few more to upload if forum users on here have issues viewing these two photos.
Its just a very well struck dime. This would be classified as FSB or Full Split Bands, that means that the parallel bands are fully struck and visibly separated. The weakly struck pieces have the bands fused together. Sadly it appears your coin has been cleaned.
I'm not certain about the center bands. Perhaps a better picture would help. On a different note based on the appearance of the S mint mark your coin may be a verity called a trumpet tail. Careful examination of the coin in hand may help with the ID. 1943-S Trumpet Tail MM FS-511 Photo courtesy PCGS.
A well struck 1943-S Mercury Dime. In my opinion it is close but does not make split bands. A very common date.
Better pictures yes, but they are rotated 180*. No matter. After examining a blown up side by side comparison I have to say normal S. I'm sorry if I got your hopes up.
