Ebay seller uzdecor-com (aka musikman33) from the USA sells a lot of decorative Uzbek items and I believe everything comes directly from Uzbekistan.
Since the middle of 2014 he has been selling plates that came from Uzbekistan but he knows nothing about them really. One collector asked him and that was his reply. He then started claiming that all his plates were genuine ones until in December 2014 he admitted they were all samples.
These unused Turkmenistan foreigner owned trailer plates are of a design that is slightly wrong and there are not 9823 foreigner owned trailers in the whole country never mind Ashgabat.
Whether they are samples or he had them made specially to part collectors from their money, I do not know but making them with all the same digits is very sad.
Mint genuine plates like these just do not exist from these sort of countries.
Just another dodgy dealer passing off scrap aluminium as the genuine article.
