ownership medallions

[Phil J]

I just bought a bunch of these at a estate sale--I have not seen them before--I assume the roman numerals coincide with number of Cadillac's owned?  Please educate me--also have one with no roman numeral

The Roman numerals were indeed supposed to represent the number of Cadillacs owned, but GM was not too fussy about this. My father's first Caddy was a 1985. After he bought his second one in 1989, they sent him an emblem with the numerals VII on it.
