The govt doesn't like competition not necessarily counterfeiters. Those old coins aren't competing with any current govt money printing so no problem as far as they're concerned. You think coins are the only thing China rips off? Try producing any product and they'll have one produced at a 1/3 cost in a year. Copyright? ha!

Don't ever assume govt does what you think it does. You have problems, they have plans but solutions aren't one of them.
