You pose an interesting question about the leather. My father stored coins in all sorts of materials, including leather. Some toned, some didn't. With leather, one the causative factors might include what it was tanned with. Vegetable, aluminum, chrome, or some other compound. Probably more important would be where the purse, visa-vi the coins, were stored. Dry, damp, UV light, etc. as well as other possible environmental elements. As far as value with toned coins, condition comes first, then personal preference for toned coins. Everyone has their own likes and dislikes. Beautiful coins IMHO.
