Jim Dawson of Florida sent in a 2009-P Puerto Rico quarter that shows multiple die chips and die breaks on the reverse. The most prominent is on the top of a cloud and folks on eBay have been offering these as having an “extra cloud.” Please believe me, this is a die break and not a cloud.
John Benton of Utah sent in four different 2007-P Wyoming quarters. They all show a multifaceted die break on the upper left side of the rider’s hat. Three of them exhibit a die crack on the obverse that runs from the base of Washington’s bust through the “Q” of QUARTER to the rim. Interestingly, they were also all struck through grease that worked itself from the peripheral tooling into the dies. In this case the grease covered areas of both the obverse and reverse dies. Notice how the offending grease migrated upon the coins with each one representing specimens with possibly dozens or more strikes in between that would have shown the progression of the migration more precisely.
