Welcome From The Heart Of Dixie. The best way to make sure you did an original is dig them yourself but most folks can't do that so in collecting them you want to do 3 things RESEARCH RESEARCH and MORE RESEARCH. If you are buying US then try and find the puppy paw backs or ones with the makers marks. This will get down on the repops by 99%. As far as the licking of the plate goes that
@Billw12280 referred to, I only do that on CS plates. When folks try a fake a dug CS plate and put a fake patina on it the chemicals have a VERY acidic taste. Please let us know if you have any further question as were always here to help.
