in indiana i think my firebird had to be 25 years old before i could get an antique plate for it and even then and a friggin sherriff actually came to check the vin numbers and stuff before i could get the plate - i thought that was a little eccessive but whatever - then it expired when i wasnt driving it for a while so when it was time to get new plates i didnt even bother with the antique plates again - ive never even heard of collector plate

got this off wikipedia:

lists antique, historic, and classic, but i see nothing for "collector" or low production # vehicles
