Ah, tricky. It's the shared reverse of the Barber Dimes and later Seated Liberty Dimes. The surfaces to me look more like a Barber Dime, so that is my guess.
My first thought was an early Flying Eagle Cent. I used to collect "Indian Heads" and "Flying Eagles" and had all except the elusive 1856. EDIT: But it is not a Flying Eagle Cent. Methinks @Mr. Numismatist is correct. It has to be either a seated or Barber dime because the wreath's ends droop downward and actually touch rather than go straight across and leave a gap as on the Flying Eagle reverse. But to be ornery... ;-) ...I'll vote for a seated dime rather than Barber.
Yes, Barber or Seated dime was my first thought. I don't know how, if it's possible, to tell the difference based on the reverse, so I'll just go with Seated.
Waiting for @KBBPLL, @Treashunt and their Seated/Barber buddies to weigh in with the precise date range, if not the actual date and mint mark.
Tough one! Barber dime reverse was my first thought but it took a bit to confirm it. Would be much easier if you used the bottom half! Fun fact - the 1891 Barber pattern dime in the Smithsonian just straight up used the seated liberty reverse.
Not a seated liberty guy but they moved the motto to the obverse in 1860, which is the reverse Barber used. I don’t think there’s any way to ID the date or MM of a Barber from that snippet but it might be possible to say pre- or post-1900.
