Question to Escrap buyers about IC chips

PartTimeScrapper compiled a great sticky thread at
http://www.scrapmetalforum.com/showt...light=ic+chips

The 5th to the last picture has the caption:
"This is a pic of all different kinds of EPROMS/IC CHIPS/FLATBACKS. They all sell for same price."

There are 4 chips around the lower right of this group that are often attached to heat sinks.

A couple of questions:
What are these chips called?
Can I get additional confirmation from any buyers that these are valued at IC chip prices? I believe I saw a comment on another thread long ago that these are not of any notable value.



I'm in the process of cleaning a pile of heat sinks and these accumulate pretty quickly. I was wondering if I need to keep these separate or just dump them into my shred pile.

If they are the ones with lond leads and a hole at one end, they are power transistors. Not really ICs and not sure about the PM content.
