I'm not sure which part is in question.
Regarding this VIN plate, I would think the only value is to be used as a novelty key chain trinket or xmas ornament. Maybe $20 or so.
As for replacement VIN plates for restoration, that was one of the first thing bought from Coupe King.

They stamped it with my VIN. So if I choose to use it on my "fully restored" car (we'll see how long that takes), it will compliment the otherwise pristine engine bay. Of course, I will have the original VIN plate (in a nice little cloth bag) along with the chassis stamp and steering column plate that all match and prove the car's origin.
That's my logic.
