For LEGO fans, collectors, and investors, retirement dates are a crucial part of the hobby. When a LEGO set retires, it means that production has officially ended, and no more units will be manufactured. This often leads to significant changes in availability, pricing, and demand in the secondary market.
A lot of LEGO enthusiasts also use Price Per Piece, or PPP, to value the set(s) they want to purchase. Though we’re not a huge fan of this metric we find ourselves doing the same thing all the time. The value of the set should really be – is the price worth the amount of time, fun, nostalgia, play or display opportunities and does your wallet agree.
The problem with using PPP to value a LEGO set is the consideration of piece type. You may have a set with a great Price Per Piece value, like set 31212 The Milky Way Galaxy with a PPP of $0.06, but the majority of those pieces are small 1×1 tiles and common pieces. You also have to consider special molds, minifigs and intellectual property (IP) licenses. For example, set 75434 Battle of Felucia Separatist MTT has a higher Price Per Piece at $0.16 but it’s Star Wars, comes with a couple minifigs and a bunch of droids, it’s cool and we want it for our collection.
