In November 2016 Ebay seller collectjj1 from Lexington, Kentucky in America was selling these reproduction early Kentucky plates from 1910 to 1913.
I do not know if he has several copies of each plate or other serials but he is correctly selling them as reproductions. They are painted on steel sheet whereas the genuine plates are enamelled (or porcelain as Americans call it).
The genuine plates are very, very rare and most are very expensive. Some people want a reproduction in their collection because there is no chance they will be able to find or afford a genuine one.
The problem is going to come later when some of these plates get into the market or crooks try to distress them and claim they are genuine. From a photo during a sale or trade it will be very difficult to tell if the plate or plates are genuine or not.
This just makes everything difficult for everyone. Reproductions are very bad for the hobby and if you care about the future of the hobby, it is better you do not buy reproductions..
If anyone knows of others he has made or wants bigger pictures of these ones, just get in touch.
