Each is 1.75" with a metal back and fixed horizontal barpin although the pin shaft has snapped off of the 1933 example. Conditions are otherwise as follow: 1928 slightest age tone on the white panel and a slightly flattened edge at the right. Still displays VF. 1929 is Exc. 1932 has tiny raised bump at center right caused by the reverse barpin but is totally clean. 1933 is also quite clean although with the missing pin shaft and reverse has short hairline streak of color but not showing at all from the front.
