How Rare? Asking for additional information

Hey Guys, I picked up another 73 Duster 340 and trying to figure out how rare it is. Its painted JF1 Mist Green. I've done some searching myself... The Color is hard to find information on.. Its a 1 year only color and 1 source says 250 were built in that color. Which equals out to like 1.7% as Mopar likes to use the % format.......And then researching the V21 option only turned up quotes of it being rare for the year also. Any additional information that other members can provide would be much appreciated.

Here's a Run down of the Fender Tag:

I also found the Build Sheet for the car...Its alittle rough, I'm in the process of recording the codes over onto a user-created blank for my personal records/showing.
