All of the seated halves from 1879 to 1890 are very scarce, with mintages of ony a few thousand. This one and the 1887 are especially so. This is a nice certified example graded XF-45 by NGC. No real issues to note.
NGC has graded only 87 of this date in all grades, and only two at XF-45. NGC's verification page for this coin can be found here: https://www.ngccoin.com/certlookup/2653658-013/ (link opens in separate tab)
