These 16 RAM memory chips are older memory modules from older PCs and one Laptop.  When my office recycled the machines, I took the memory out because I knew how expensive they were when we would upgrade memory over time.  I have been saving these for no reason.  I cannot verify if they work, but they worked fine in the machines at the time.  If you are a computer geek and could use these in your hobby or work, please bid.  No reserve.
