Toning should be a natural occurrence built up over many years, artificial toning is possible & more & more coins are appearing for sale that look like they have been artificially toned.

Natural toning is the best. Putting the coin in the open air and sunlight is the best. Take a block of rigid foam with some pins pushed through to support the coin with maximum exposure. Flip the coin after 3 or 4 days. It may take several weeks.
