I recently received a NISB Rio Mascots set as part of the prize for the October Monthly Building contest and I have a very hard decision to make: do I keep it sealed and sell it? Do I keep it sealed, wait a couple of years then sell it? Or do I just say "to heck with it all" and build it? It's a neat set, but it's very rare and somewhat pricey, so I'm looking for some advice. I'm not used to dealing with sets that are as rare as this one. What is the interest level in this set? What do you think I should do? Any advice is welcome!
