Mineralogical records: how much to price 18 years' worth

Trying to figure out how to sell my dad's 18 year run of Mineralogical Records and also how much to price it for if I throw it on Kijiji or Marketplace. He has all issues from 1978 to 1995 inclusive as well as some from 1977 and 1976. I do not trust AIs answer and I don't think anyone would want to pay for eBay shipping as much as auctioning would be easier. Thank you very much
