how do you date tech deck toys?

Ok I have the following Tech Deck boards new in package with all the trimmings. What I want to know is how do you tell when they were produced or made. I have the ones as follows, Baker, Blind Dark Star, Finesse, Flip, Foundation, Plan B, Powell and toymaker. I dont know what to do with them. over 200 packages.

Possibly check the back at the very bottom for a copyright date. I don't have one to check, so idk, but that's where I would look.

That's a good question. I've got a couple of really old ones, like from when they first came out, still in the packages.
