@justinmew, I personally am not a huge fan of those sets, I think that LEGO has overvalued integrating technology like that into their products in the past and this seems to be another example of that. I think the sets would be significantly more popular if they were to traditional minifigure scale and not the big figs. That being said it is hard to bet against the Nintendo/Mario IP and I wish the theme success so we get more crossover sets for years to come.
@muk, those are beautiful sets, and even though they are before my time I can still appreciate them for how innovative they were at the time. The monorail especially is a favorite of mine. If I were to purely collect a sealed set it would be something more classic like those because the built and displayed appearance is not nearly as stunning as some of the more modern sets but the box art is incredible. #graphicdesignismypassion
@brendantheclayboy, nothing wrong with inspiring a new hobby, glad you found it so cool you want to take a closer look!
@thedude1990, There are an amazing number of couples who use it as a way to spend quality time together. I think it is a little harder pinning down the 1st ed Charizard or Illustrator of the LEGO world like @scarecrowman88 said. Historically I would say the 10179 UCS Millennium Falcon (Original from 2007) would be the holy grail because it was the most expensive set for a long time and appealed to such a large audience. For minifigures I would say it is a Mr. Gold from series 10. Only 5000 were produced so it is very rare. With that being said, I think you could consider a lot of things a holy grail. There are many other rare sets and minifigures such as those released at comic con, or even a sealed copy of any of the sets a couple of posts above yours might be considered a holy grail. But it really is an individual preference.
@justmatt, That’s awesome, you should post pictures of the unwrapping if you can!
@pokemontrainerdutch, There are many different factors so it’s hard to make a 1:1 comparison, yes there is a larger margin grading a $20 card for $10 and selling it for $200 but that is becoming far less replicable by the day. What LEGO investing does have is the ability to easily replicate. You can purchase multiple copies of a set for a large period of time and it is widely accessible so it may be attractive to many different kinds of people. I think the growth that cards have seen in the past year has been incredible and I have also benefitted greatly, but there is nothing wrong with diversifying.
@zorloth, It looks like you started to answer your own question before I could respond so good on you for that. You are right, buying used and “parting out” (or in this case piecing together) a set may be a more cost effective method. I see where your confusion lies and perhaps I will edit the main post later but let me do my best to explain here. A part out value does act like a glass ceiling for many sealed sets and it helps draw prices upward but that is mostly for new pieces. However, in more extreme cases such as your example, the uniqueness of the pieces in the set is so abysmal that they are hardly worth anything (the pieces appear in many different sets and therefore are more commonly obtained). The other major factor is buying used parts. Used pieces are a fraction of the price as new ones. When I enter that set number, 3219, into the part out value box and search for new pieces the last 6 months sales data is $4.73, when I do the same for used it is $.79. I think that price would be a more accurate one than the $.25 you had mentioned without factoring in things like shipping. You are definitely on the right path comparing used complete set prices to part out values. The other thing you can do on bricklink is click the part out button below “My Wanted List” on this page: www.bricklink.com/v2/catalog/catalogitem.page?S=3219-1#T=P That will allow you to add all the parts you are needing to buy from a set and bricklink’s algorithm will check for sellers who have the majority of pieces on your list and try to optimize your orders. Let me know if there is more I can clear up or elaborate on.
