Vigier Guitars

Hi.  I'm shopping for a new Vigier...Excalibur with a floyd, specifically.  Kind of concerning, I'm finding two Vigier guitars with the same serial, 170088  (Google  'Vigier  170088', you will see them both, at ostensibly reputable retailers).  One a yellow and black rock art, the other, a pearl white Supra.
 
Are Vigier serial numbers unique, or may they be repated across models?
 
I can post the links, but i'm not sure if it is allowed on the forum

It is mistake from our plate supplier that we did not see imedialtely. There are some Excalibur with the same number, that's what make them "unique"

Thank you very much for the clarification.  I knew that it would be difficult (impossible) to 'counterfit' a Vigier, however, I wanted to be as sure as possible before I purchased the guitar.
 
Have a wonderful day.
