About the 1966 quarter
The 1966 quarter is a regular circulation issue, struck in copper-nickel clad copper, weighing 5.67 g, 24.26 mm across, from a design by John Flanagan. 821,101,500 were struck at Philadelphia.
For scale, 1966 mintage was 55% lower than in 1965, when 1,819,717,540 were struck.
The spread on this date is almost entirely about condition. A worn example is $0.25; the same coin certified MS68 carries a guide value of $7,250, and PCGS has graded 9 that high. Everything between those two numbers is a question of how the coin was handled in its first weeks.
Population figures put that in perspective. Across the grades listed here PCGS has certified 3,709 examples of this date, and only 9 of them reached MS68. A coin that spent years in a till will not be among them; one pulled from a roll and never touched might be. That gap is the whole reason two coins with the same date sell for very different money.
There is also a record of what people actually paid. The highest recorded sale for this date is $504, at Stack's Bowers in June 2024. Auction results move around the guide values rather than matching them — the same coin can bring more on a day two determined bidders want it, and less when nobody does.
