Masters of the Universe Eternia Playset ($2,000)
There are so many collectible He-Man action figures that are worth a small fortune so it is hard to keep track of all of them but this set is one of the most sought-after and is quite expensive. The Masters of the Universe Eternia Playset is a set that collectors are willing to pay big money for.
This set contains several figures and was only produced in limited quantities making it even more collectible. This set is valued at about $2,000 in mint condition and is worth even more if it is brand new. There are not many that survived so finding one of these is the holy grail for certain collectors.
