Purchased directly from James Sego, which at the time was the #1 set of Eisenhower Dollars on all circulation strike sets.
This is the last year in which they struck Eisenhower Dollars. Coins are very common and up until the 1990's the coins could have easily been found in banks and even in circulation. In grades of MS66 they become scarce with possibly less than 1,500 examples known. In MS67 they are almost unheard of with less than a dozen known.
