We know very little about the actual interaction but there's no claim I see that there was coercion when the coins were sold to the undercover cop. Cops are allowed to setup chances for people to do illegal things, that's what stings and bait cars are all about, basically the fact that the person is a cop isn't really material because there's the assumption the person would have committed the crime with another person in the same situation.
