I went back through some emails from a few years back and came across one from Gary Plowman about Coronado Gold.
"Mike, coronado gold was a spring color in 67. It was a special paint as all the spring colors in 67. They painted so many cars of each color and sent them out throughout the country to see what color combination would sell for 68. Coronado was one that did not make production for 68 so very few were made. Mathematically speaking I would say there were only around 70 total conv. made. I know of at least 6 or seven cars with that color and only maybe four that are conv. so the color code O on the tag makes it unique.

Also interesting, is there are currently 12 coronado gold cars in the online car show. This does not account for any cars that may have started out as gold but now changed and/or not noted as the original color.
