In February 2017 Ebay seller 27597 from Raleigh in North Carolina, USA was trying to sell this sample Saudi Arabia plate. He say it is used but „like new“. It is not, it is a manufacturer’s sample.
It is made of steel and the real ones are aluminium. The black border and outlined circles are wrong also. It is probably a sample from when an American company was trying to win the contact to supply plates but they did not get the contract.
Always check that a plate is close to that particular country’s genuine plates. There are several websites like Francoplaque (www.plaque.free.fr) and Plateshack (www.plateshack.com/y2k/) that have good pictures of genuine plates.
Be very suspicious of every plate these days and check the web sites.
