The toning is natural in my opinion and yes the older coin folders and even some of the newer ones can cause a coin to tones like this ,, especially if the environment is not controlled, Humidity ,hot and cold, and chemical reactions with the sulfur and other chemicals in the production of card board and paper make toning such as this ,,sometimes colorful and pretty sometimes black and not so pretty .
