Ike Dollars struck on clad dime blanks are excessively rare with an estimated five pieces known. This Ike Dollar was double struck on a clad dime blank with the second strike 80% off-center, die struck both sides. This is one of the ultimate Ike Dollar major mint errors that has ever been discovered. It recently came out of an old mint error collection that was assembled over thirty five years ago. I had the pleasure of purchasing this collection and was excited that this specific piece was included. It is certainly unique and worthy of any Ike Dollar or mint error collection.
