Where did my memory go?

Tonight I dug out all the old computers, and realized I scavenged most of the RAM out of them a way back, as well as stuck any extra memory sticks in there. Specifically, I had two plastic bags with a bunch of old sticks of memory.

So where are they? Where is that memory? Is it in the spare bedroom, shortly to become Alexis' room? Is it on a shelf in a closet upstairs? Did I give it to a friend on a whim, thinking it was past the shelf life, and good riddance?
