This coin is in great condition – I’d consider it EF40-EF45.
On the obverse, you’ll see Liberty facing to the left with lots of loose hairs peeking out from under her liberty cap. The legend reads “Republica Argentina * Libertad *”. The depiction of Liberty reminds me a lot of the Morgan liberty dollars, although she has a very Barber chin.
On the reverse, there’s a boring wreath around a number 1 (although the number has some neat raised borders that are resistant to wear) and the denomination “Peso” and the date at the bottom.
