Is LEGO worth investing?

What is LEGO?
Lego is a popular line of construction toys manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colourful interlocking plastic bricks and an accompanying array of gears, minifigures and various other parts. Lego bricks can be assembled and connected in many ways, to construct such objects as vehicles, buildings, and even working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.

Value?
Like any other type of alternative investment, LEGO depend greatly on adults who is sentimental on it and from the popularity of this toy, the sentimental value is quite high even for some of the simpler model.

The value of the LEGO will also increase base on the rarity and the quality of it. A high quality and limited collection LEGO might double it value in just 1 or 2 years and since LEGO companies tend to stop production on certain model after a few years, the rarity increase as the model get older. Sometime the value increase in 10 folds.

Liquidity?
The market for LEGO is surprising huge, letting go of a model should not be har.

Growth?
This is hard to measure as it will be based on sentimental value with no real system of gauging the LEGO values. Certain model like modular house do better than other model but there is no certain way of telling which LEGO will do better in the long run.

Advice?
Get limited edition, high quality, long running movie/cartoon/comics series toy and never remove it from its box. Once out of it box, the value tend to drop more than half.

Trading LEGO while it there is a cartoon or a movie series on going, this will improve the liquidity.

Does it make good investment?
The value of a LEGO is hard to predict and usually hard to find a buyers as this is mostly base on impulse buying. But as the follower of LEGO is quite huge, as long you are willing to hold on for awhile, selling off a model shouldnt be impossible.

For long term predictable investment? No it will not make a sound investment as it is unstable and tend to take up alot of space but it will be fun and entertaining to explore your childhood dream of owning a Lego Mixels!
