Leave it in and let it continue or take it out and put the coins in flips? An inexpensive set that is toning due to the holder. Will probably hang on to it but should I care about the toning? Took 40 years to get to this point. Will another +/- 30 years of toning matter much?
No. Given the current progression, I seriously doubt that you'd live long enough to see any change at all.
Kind of what I was thinking. Worse case, colors go crazy due to change in storage location. Cannot imagine it would hurt the value of inexpensive coins to start.
Here is a picture of the two sets and 1 of the COA's. I don't think you can tell because they are in these holders?
Just curious looking at the quality of the IKE if it was an early white stripe one, or the "mass-produced" no-stripe bicentennial pack. If you have them glued into the holders you'd have to destroy the OGP to tell. It's not that big of a deal. Just curious for myself. The white stripe is along the edge if there is one. It's quite wide. Can't miss it if those aren't glued in.
