Not sure Readers Digest wanted to educate anyone, since they relied on stupidity, but indeed, the line between intention to deceive and no intention to deceive is blurred. Medals with COPY or the initials of the maker (like WR) are in my mind free of suspicion, but when Chinese manufacturers fill whole web sites with fakes that do not have any indication of their status, it doesn't matter if they sell them for fakes. They sell them mostly to people who have bad intentions. Institutions and people like Northwich Auctions that knowingly sell fakes are fraudsters and should be punished, but where would they be without the fraudulent coin/medal? They don't have the skill to make it themselves and may even find that too risky.
So yes, kick the Northwiches where it hurts whenever you can and as hard as you can, but don't forget that under current trade laws, they can buy as many fakes as they want from equally repulsive, but legal producers. Laws need to change.
