We have here four (4) different varieties of Boston Braves World Series Press Pins. 1) Bronze colored threaded post type which is missing the screw on the back but has the post. 2) Silver colored missing the post on the back. 3) Gold colored with rough pinback and Balfour stamping (may have been made later than 1948). 4) Gold colored with smooth pinback and no stamping (may have been made later). Except for the issues noted above, all are NRMT.
