1970 e-body fender tag authenticity question

i was looking at a 1970 challengers fender tag recently and noticed the VIN was on the second line from the top instead of the usual bottom line.

i was looking as i have very good doubts on the cars authenticity and the owner got rude as i questionned the cars fender tag...

was i looking at a very poor quality ''fake tag'' ??

Obviously the owner did not want me taking pictures of the tag

Without a photo or code layout, it would be hard to say for sure. I guess It's possible to have a mistake or the VON number the same as the VIN, but that would be like one in a hundred thousand.
