[cctalk] Old vintage computing magazine/newsletters

Just a 'survey' sort of question - how much value do you guys put in vintage copies of old newsletters, magazines, etc. I'm talking mid-1970s, like People's Computer Company, etc. Someone has been selling them one at a time on ebay and they routinely go for $125+ each! Was PCC fairly low circulation? I have no idea how rare these things are - if I should just dive in to have my memento or wait. Looking at auction history it seems to be the same group of 2 or 3 bidders going nuts over them. One newsletter I would love to find an original copy of is Micro-8.. but I think the circulation on that was just a hundred or so, so probably unlikely. It has some blurbs from Grant Runyan in there, who built my TVT and Mark-8. But yeah, I just wondered if you guys think generally this stuff *should& be considered valuable - given most/all is archived online. Brad
