Any value to old various dealer mail order world coin lists 1980 thru 2010

Does anyone use these for research or?
I see catalog nuggets in them things/ groupings/ sets/varieties I would never know about.
Anyone keep or use such? Or can now all this be found online maybe?

check with Newman Numismatic Portal if they need them. https://nnp.wustl.edu/
They can scan them and add to their library for everyone to access.
Most of those lists have a nominal to no value. Quite of they provide examples of prices from years gone by. If they have any important coins on them, it might help in establishing a list of prior owners.
