In October 2016 Ebay seller jbeerd from Moscow in Russia was trying to sell these DPR (Donetsk People’s Republic) replica plates. He is selling them as replicas (which is good).
The biggest danger is that some crooked dealer on Ebay will buy them, distress them and then try to sell them for a profit claiming they are genuine.
A true collector wants genuine plates. Why fill your collection with replicas that cost about 15USD to make and you had to buy for maybe 100USD. Why not collect photos instead? It is cheaper and you will get a bigger collection quickly.
Do not buy mint plates. It does not matter if they are cheap, almost all replica plates have something wrong with them and are really just scrap aluminium.
