Those are all fairly common. Not worth very much, I'm afraid. If you find any RCA 4000-series CMOS parts from the mid-'60s with round lids (see below), or any of the above in pre-1970 flat packs or TO-5 style cans, they'd be more collectible.

I wouldn't mind mounting a few of those on my chip collection board.
Are any of them gold plated?
When will you be listing any? |

Not sure if you were talking to me or donutty... The RCA chips have gold pins, but the lids are Kovar. TI 74xx flat packs, OTOH, are often gold-plated.

| No flat-packs, no round-lids (I'm keeping those ones). Just want to clear some space. I'll list them in the 'Other' For sale forum. |
