In February 2016 Ebay seller bmw7777777 from Surgut, Tyumen region, Russia was trying to sell these plates.
They come from many different countries and all are made-to-order specials, salesman’s samples or rejected test designs. They are all mint and all have something wrong with them.
On some plates the flag is wrong, others have printing instead of embossing or the font is wrong or the spacing is wrong or the wrong base has been used. Some are known made-to-order specials from Chinese companies that were sold in 2015 by other dodgy dealers in Ebay
If you buy mint plates like these you will end up with scrap aluminium in your collection.
