Is It Illegal To Buy DPRK Coinage?

Which when they're that interpretive, I can see why they would just cut the whole thing off and say it isn't worth it. If the lawyers thought Cuba was a minefield they must have lost their mind over that. Not to mention they probably have very very little incentive to even try.

I know it's kind of frustrating overall but this is one of the things I actually do sympathize with them where just saying no to everything is easier.

There are venues where these things can be sold legally as they know where the object came from which really is probably the big issue with ebay and PayPal in the sense that they basically never take possession of anything for a sale

Some DPRK coins, at least some, were indeed struck in China.
Ask a knowledgable DPRK collector to clarify which coins.

I collect South Korea, and I do not like North Korean coins. North Korean coins are queer in the deepest way, both in design and in use.
North Korean coins are not really money in an authentic, decades-old, full-functioning economy like that of South Korea's.
Their coins are used to bring in foreign currencies that help them fund certain priorities such as their missile and nuclear programmes, along with allowing the Kim family to keep functioning its abattoir of a state. Honestly, the DPRK makes more money off of other twisted things, and I'm sure coins aren't doing much of the heavy lifting when it comes to bringing in wealth.

However, when it comes to others who collect them, I just say, "each to his own."
