Probably they are stabilization prints.  It was a machine method of  processing that delivered fairly dry prints in a few seconds.  They were not run through a fixer.     They should not be stored with other prints, and in time they will fade, (a matter of years) unless they are fixed and washed.   There were several brands of processor, but the most popular was Kodak Ektamatic.   I think the back of the print will say Ektamatic Paper.   Agfa, and a couple other companies made the paper as well.
 
Here's Kodak's recommendations:

Subject: [ARCHIVES] Smelly photos

We found some photos damaged by moisture that smell bad.  They were probably taken for the yearbook in the 1970s.  Some but not all the photos are in the yearbooks.  The subjects are unidentified.  Should we throw them away or keep them separate from other photos?
