Good info thanks David.
Barring extraordinary demises, I think our cards are going to last a lot longer than any of us will.

Interestingly, before canvas, paintings were usually on wood. The Mona Lisa is on wood.
Dust and dirt and exposure is a big cause of damage, so entombing them in a holder is likely decent protection for cards for long term. Though probably sealing them from air between acid free sheets is probably the best.
As mentioned really old paper can last better than a lot of modern paper, because rag paper doesn't deteriorate while wood pulp in modern paper does. However, many modern artworks, including prints, are on rag paper so should last well.
