This is a semi-key in the One Peso series with a mintage of just over 3M. How many survived in this condition? This is a $30. Book value coin in Ef, with a graded population of LESS than 40 coins! Compared to a Barber Half dollar of the same year, with a mintage of 2.4M, and a graded population of over 1000 coins, AND only 10 to 15% of the value, and i'd say this is pretty darn cheap! EF+ Several available.
