collecting silicon wafers

Before anyone goes in trying to cash in their wafers...I assume any
wafer that was not kept in a clean room environment is worthless. The
couple of wafers I have finger prints so they definitely are worthless!

Hi
 Even wafer collecting can have monetary value. A while back, at
the beginning of the last Middle East action, there was a military
requirement for mil spec TTL parts. I don't recall which but
I believe it was 74139's that were in short supply. Anyone
with a wafer of these could just about name their price.
 The fact is that most companies consider the wafers as
proprietary information. They would rather destroy it or send
it back to the foundry to be recycled. Wafers that do make
it to the outside world are usually from some company that
has shut down and had a warehouse of overstocks.
