To view more detailed information on the collection click hereDie Variety: The obverse die has a thin top to the 5, which is even with the top and bottom of the 2. The left base of 1 between dentils, 114 dentils on the obverse (previous 100 and 98 dentils seen). The reverse die continues from 1821 with the 1/2 fraction digits distant from the fraction bar and large D in denomination. The 1825 quarter eagle has a mintage of 4,434, and incredibly, three different die varieties are known. BD-1 and BD-3 are represented by a dozen or so coins; BD-2 is more plentiful, as 80 to 100 are known.Die State: a/a. Both dies are free of any cracks or clashing evidence. The obverse die was retired after the short-lived production of this variety; although no reason is known it must have suffered a failure to require replacement or it likely would have been used again in 1825 or later.Estimated mintage for the variety: 250 to 750 coins out of 4,434 struck of the date. Estimated surviving population: 12 to 15 coins.Strike: The obverse devices are all boldly struck and the fields show nearly full reflectivity. Examination of the reverse finds a matching bold strike on the eagle and shield, but with some lightly struck areas seen in places.Surfaces: The attractive surfaces hold up well under examination, and the delicate mirror fields show only light handling evidence with no distracting marks or nicks. Attractive toning blends crimson-copper over deep orange-gold on both sides. An outstanding rarity in any grade, this pleasing Mint State coin is undoubtedly one of the finest known of this rare die pairing. Commentary: One example exists in the Harry W. Bass, Jr. Collection that was first struck about 50 percent off-center, and then struck properly a second time. Traces of the first strike are present, and this coin is plated in the Bass-Dannreuther reference on page 96. Q. David Bowers: This is a lovely example of the variety. Likely, as the Bass-Dannreuther text increases its distribution, interest in die varieties will expand.John W. Dannreuther: The BD-2 variety for this year is available, so the two rare issues have seen little demand, as collectors can obtain the date. However, this BD-1 example and the BD-3 two lots later are true rarities. Both varieties are nearly R-7 and if they were in heavily collected series such as large cents, they would be mega-rarities bringing mid six-figure prices. The astute collector will recognize that such quarter eagle rarities will be more appreciated as time passes.
