527 single dot

Question: why are these not listed on the date guides? What year were they?

Welcome to the Buck Forum. Good question, the most recent Buck Collectors Club Newsletter has a small article that addresses the single dot as an Engineering Change Notice, from the 1984-85 era. Joining the BCCI allows you to enjoy countless benefits :thumbup:
