Like the title says, if you happen to know, how many pieces do you currently own?
I've been working at updated the "my sets" database for my profile on brickset.com. I'm almost complete. My total pieces count is currently at 126,627 pieces. However I still have a couple basic brick sets from my childhood (mid-late 70s) to add to my list. I also have to make sure I've properly accounted for any sets I may have sold over the last few years. And that doesn't count the half dozen (at least) cups of pick-a-brick wall excursions that have also added to my overall pieces stock.
Its probably fair to say my real total is at least 128,000, maybe even pushing close to ~130,000 (but not likely more than that).
It's kinda funny... a relative small percentage of my total is from my original childhood lego. The remaining ~120,000+ is from the last ten years as an AFOL after coming out of the dark ages.
Let's hear yours.
