1965 Quarter Mint Error (1965 25C Mint Error) NGC AU55. Silver planchet transitional error. Struck on a 90% Silver Planchet. This silver-grey transitional 1965 Quarter shows some mint luster in the devices on the obverse, more so on the reverse. The obverse shows light toning in the field under LIBERTY and on and under Washington’s chin and the front of his neck. The reverse shows slight toning in the field. There is light abrasion and wear on both sides of the coin in keeping with the grade. The strike is average on both sides.

The year 1965 was the first year of clad coinage, hence the transitional nature of this error. The outer layers of this coin should have been composed of copper-nickel which was to have been bonded to an inner core of pure copper. Clad quarters weigh 5.67 grams. The present coin, which is made of 90% silver, weighs 6.26 grams, the approximate weight of the 1964 quarter. Evidently a sliver planchet remained in a tote bin crevice and later was dislodged and mixed in with the clad planchets. Specialists call this type of coin a Wrong Metal error.
