Hello and I apologize if this has been discussed before, I tried searching the forums and didnt find what I was looking for. I recently started really going through my old coin collection that I received years ago when my father passed. He and I would collect coins when I was a child but stopped due to personal reasons (among them being my own ignorance and stupidity as a young kid). Anyways, I have been going through the couple of boxes of what I have to see if anything is worth keeping. (the collection was damaged when I received it while my father still had them due to his basement being flooded and the boxes they were stored in got wet. most of the damage is to the information sheets / paper / cardboard holders that the coins / mint sets were being held in, (see the attached pictures) from The "Postal Commemorative Society". the paper / cardboard sheets are all water damaged and the mint sets look to be in questionable condition. My question is are they still worth keeping in the original cello holders, or would it be best to remove the coins and place them in protective flips? the attached pictures are only of 2 of the sheets but I have sheets ranging from 66 to 2000 (missing only years 1982 & 1983). I removed the sets from the sheet since the sheet was water damaged.
thank you for your time and input!
