664-Ebay aucon1 Austria army fake replica number license plates

In November 2017 Ebay seller aucon1 from Austria was selling these 1967 series Austrian army plates. He does not say if they are used, new, genuine, replica, etc and they are very expensive.

They are replicas and the font is not quite right.

Why even think of buying mint plates without checking to see if they are genuine or not?
