My "collection" stated with the original black/yellow California plates that were on my car at the time of purchase that I sent off to "that guy" in PA to have restored. It only took 3 years, but they are really nice.

Then I got a set of '67 plates for Texas, cleaned them up, touched up the paint, then clear coated them with a satin finish. But I moved to OK.

The OK '67 plates have just been sitting in the envelope they were shipped in as they were in great shape. The bizarre YOM rule in OK was that I would have to keep the original "modern" plate someplace in the car. But then I moved back to AZ.

The never used '67 AZ plates are just waiting for me to go to the ADOT office to officially swap them out and pay the YOM fees. The car was so far from running during my 1st stint in AZ that I never got plates for it that time.

Another weird note is that OK changed their mainstream license plates 3 times during the 8 years I lived there. They just could not seem to meet the Fed criteria for night reflection.
