this is a grey aread. up to this point, we have been strict about not allowing counterfeit currency, but all kinds of counterfeit things like bullion, apparel, even fake drugs have started to be sold on SR and we just haven't taken the time to police it or draw a well defined line for what is and isn't allowed. At this point, you won't be stopped if you list this item, but sometime soon I will have a discussion with the community about where we want to draw the line and you might be asked to delist such items. If that's the case, anyone selling such items will get their bond refunded even if they hadn't met the requirements. Hope that helps clarify a little.
