In February 2016 these plates were being offered by Ebay seller vehi-vehi from Sarajevo in Bosnia and Herzegovina. You can see where these mint plates have been wired onto a display board presumably in the police plate issuing office in Sarajevo. They are very similar to the plates that together5882 and amirenduro2013 were selling and have probably come from the same place.
The Dubai plate is a 1996 Utsch salesmen’s sample that were often given out with this same number to plate factories around the world..
The Palestine plate is a test design and has a wrong type of registration
The EUR plate, that he says is the EU Council in Bosnia, is a fantasy design and the EU have never used anything like this.
The Mongolia plate is a test design and has the wrong graphic at the left.
These are all manufacturer’s samples and rejected test designs given to the police when the salesman was trying to interest them in buying from his company.
If you buy mint plates like these, you will end up with rubbish in your collection.
