Lovely album toning of orange, rose, pink, blue and teal graces the obverse, while the reverse remains essentially untoned. One-sided toning is often found on bag-toned and end-of-roll coins, as well as some album-toned pieces. Other types of album storage may result in two-sided toning, which is also the norm on envelope-toned coins. (It was once commonplace for coin collections to be stored in individual 2x2" paper envelopes.) ANR, LaBelle Sale (7/25/05:1339).
