T-BOP: I'd speculate ambient air quality -- meaning the wild fluctuations in temperature and humidity that we get here in the Northeastern US -- could have amplified the effects of the leather, not to mention off-gassing from cardboard, adhesives, and plastics that were inadvertently part of the "storage regime."

The chemicals used in leather production vary from time to time, and place to place; they include urine, various sorts of biologically active sludge (such as animal dung or abbatoir by-products), alkaline lime paste, salt, sulfuric acid, and chromium sulfate solution. Any one of which could cause problems for coins stored in them.

Yep I've seen similar results with leather coin purses. Maybe it's the abattoir by-products?  "If you climb a good tree, you get a push."

Yikes! Fortunately they appear to be mostly Memorial cents. Still an unpleasant sight...

Don't wear leather next to your skin - you may suffer the same fate as those Lincoln Cents !  |

Try stuffing coins into a well-used baseball glove and let it sit for a year.

I thought what Sap said, there are a lot of treatments most different in leather, could be any number of the ingredients used to cure, color and finish the leather, could be just the leather alone, but I'd bet it's more along the lines Sap mentioned it's more to do with whatever was used in curing and finishing the leather off.

Looks like the marble bag is in good shape though. Not a total loss.
Be glad you didn't have Indians in the bag is all I can say.

TNG, I'm just glad they're someone else's coins!
