When the mint replaced the punch midway through 1873, it created the second Shield nickel variety – the "Open 3." The "Open 3" is the mate to the earlier "Closed 3" variety. Just over 4.1 million "Open 3" nickels were struck, and with the passage of more than 130 years, who knows how many exist today? Why not add this prized Shield nickel to your collection today? Or better yet, not buy both varieties!
