Nostalgic value only. No body is interested in the retro stuff now. I was in the business from 75 to around96 and its a whole different world now.
Good to know. The magazines didn't have much value to me anymore. It was time to move on. I still have a couple of racing bicycles from the time period. The frames were handmade and have excellent workmanship... they still have some value beyond sentimental from the tens of thousands of miles that I rode on them, and many of the parts on them were prizes that I won in races. Things like my Campagnolo Super Record rear derailleur are little trophies that only I know about.
