This is a 1964-D/D Washington 25C with multiple errors. The coin is circulated and has not been graded. The 90% silver 10% copper composition gives it a unique sheen. The coin has a business strike type and is not certified, and has not been modified. This coin was produced in Denver in the United States. The obverse and reverse both have doubled die errors. The reverse also has an RPM error. This is a truly unique coin for any coin collector or coin enthusiast. My laptop is not
