    Extremely Rare Wrong Alloy Error

    1976-D $1 Type Two -- Struck on a 40% Silver Planchet -- AU55 PCGS. 374.5 grains. A Clad Ike should weigh 22.7 grams, or 350 grains. Struck on a planchet intended for 40% silver Type One San Francisco Bicentennial Ike dollars (Breen-5764). Under Breen-5770, the entry for the Type Two 1976-D, he mentions that "a silver-clad specimen turned up about 1978." A perusal of our online auction archives reveals three 1974-D and three 1977-D Ikes on 40% silver planchets, but no prior appearances of the present wrong-alloy variety. Untoned and satiny with a typical strike and minimally abraded surfaces.(Registry values: N1)
