These are more Polish made fakes that have appeared on the Polish auction site allegro.pl in November 2012.
The left hand column are all from seller docar1 and most have the wrong dies.
The right hand column is 2 Austrian fakes from docar1 (wrong dies), a Danish fake from shellby83 (wrong dies) and 3 pairs of German fakes from sebmar2 (2 pairs are made of plastic).
You need to check before you buy unused (mint) looking plates as there are so many fakes and fakers on various auction sites. Nearly all non-USA mint plates are not genuine as the countries that have officially issued plates do not give out unused plates. A few plates may be correct in every way but most are just scrap aluminium or rubbish plastic really.
Check with the big website photo archives if they are correct, ask to see a photo of the back of the plate, check on the plate forums with other collectors.
