In June and July 2017 Ebay seller life-after-work (aka life-after-work2 & eddspl8s) from Maryland in the USA was trying to sell these Greek reproduction motorcycle and car plates.
He is selling them as used reproductions. Used they are not and reproduction, yes very poor quality ones.
The font on the motorcycle plates is wrong, the plate sizes are wrong and the embossed official seals are missing.
Be very careful what you buy and don’t buy mint/reproduction plates or you will end up with expensive scrap aluminium in your collection.
This is an ALPCA member who knows little or nothing about non-USA plates and is trying to fool collectors and make a quick profit.
