Oh gosh, I don't remember exactly. Late 90's maybe? I remember my very first set of Legos being a bunch of standard bricks in a limited edition silver metallic container exactly like the one pictured. Still have it. I also have some early Lego Star Wars sets and Harry Potter sets, including the first version of Hogwarts ever released with its original box.
I also have sets from now discontinued series like Life On Mars, Jack Stone, Arctic, and an aqua-themed series whose name escapes me at the moment. I remember the villain having a gold visor, one red eye, and named ogle or something like that.
Granted they are all in various states of disassembly, but I know I have all if not 99% of the pieces to put them back together.
Someday when I am able I'll put them all back together.
Wow. I started playing with Legos when I was maybe 6 or 7.
