I am going to jump in here. The NFHS Manual has always (with apologies to the late J. Dallas Shirley) allowed officials to wear a wedding ring only. The CCA Manuals were like the same as the NFHS Manual until the late 1980s when the wearing of wedding rings were prohibited.
I started officiating in 1971 and did not get married until 1982. Prior to getting married the only rings I wore were originally my H.S. ring which then changed to my college ring and my Order of the Engineer Ring. Since they were not wedding rings I did not wear the when I officiated. When I got married I choose to not wear my wedding ring because if players cannot wear jewelry neither should I. My dear wife has never complained about it.
