Final Thoughts

Investors in the Lego sets know that a great one is worth hundreds of dollars and sometimes thousands of dollars. The idea is to obtain the original model sets at a very low original price and at the right time.

Over time and with limited production, the prices rise in the secondary market. You have an opportunity to sell at insane prices.

Massive investment opportunities exist for toy companies that have the chance to make stuff for fascinating children and adults themes as well.

Surprising things happen, and situations work favoring a set under your custody. It’s your opportunity to sell out and reap the gains.

The key to Lego flipping like the big boy is to Buy and hold for future money.

My passion for Lego began when I was a young boy and loved playing with my Lego sets. Like most kids as I grew up, I moved onto to other things and my Mom never saved my sets. (Yikes!!!!) Fast forward to when I started working the 9-5, I reconnected again with Lego and it has been a part of my adult life as an AFOL (Adult Fan Of Lego).
