These are all from one proof set. Both the Maine and Arkansas 25c obverse are strongly doubled on USOA, LIBERTY, IGWT, QD, and the mint mark on the Ark. The Alabama reverse has missing frosting on Helen Keller's shoulder and cud on her arm. The 5c obverse has "ice crystals" on Jefferson's chin giving him a Van Dyke beard. The "ice crystals", for lack of a better term are also evident on the Alabama reverse on the leaves at about 2:00. These are the best pictures I could take keeping them in the mint plastic.
