Most of the watchmen badges were very simple, this one being fancy means it was during 1907 through 1909 as it would've been used during a World Series. Which World Series I do not know- possibly all of them, but the badges of this era were very simple and I only find the special ones from the World Series or All-Star games. The condition of this badge is very good, as it would only be used for the home games of a World Series, the screw back is definitely a replacement, but otherwise it has its dings. Dents and slight scratches, but it is in very good shape looks like it might be made out of nickel. Good luck, grab this piece of history!!
