Quoted from Waxx:I would counter this thought with the fact that they only made 750 R&M and many people bought them for roughly the same price second hand well before Spooky finished making them all. It's highly possibly you get a high number and have to watch people play their pins and even sell them for retail all while you wait to get one.
Make sure you are ok waiting a year or longer to get one.
Not sure I would agree with this. During production R&M spots were going for up to $2500 premiums, and even now after the run is over, the average selling price is at least $1000 over NIB price.
Obviously, there's no guarantee that Halloween or Ultraman will do the same thing. That being said, folks always tend to sell their spots for tons of reasons, so if you miss out you can likely pick up a spot later. I'm just saying there's no guarantee it'll be for retail.
