To view more detailed information on the collection click hereDie Variety: The obverse variety shows the overdate, with the flag or upper serif of the 1 to the left of the 4. Apparently two obverse dies were engraved in 1821, but only one was needed for coinage. No quarter eagles were struck in 1822 or 1823, so when coinage was resumed in 1824, the unused die was overdated. The reverse die for this variety and year was the same die as used in 1821 for quarter eagle coinage. The serif of the 1 extends from the angle of the 4 and other indications are clear of the undertype digit.Die State: a/a. No clashing, no lapping, and no cracks.Mintage: 2,600 coins.Estimated surviving population: 50 to 60 coins.Strike: Rather sharp for this issue, with a hint of softness on the central curls of Liberty and along the left (facing) side of the eagle which is common to this series. The lettering, stars, and devices are pleasing and well formed, though most of the known examples have rather poor strikes in comparison to other issues from this type.Surfaces: Subtle reflectivity is retained in the fields, something usually seen only on the highest grade coins that were struck with freshly engraved and polished dies. The more open fields are subject to normal wear and abrasions, but here they are fresh and attractive. Lively orange-gold surfaces exhibit traces of copper around the peripheries.Commentary: The rarity of this and related issues of the decade is explained by low mintages to begin with and the melting of most coins after 1834 to capture their bullion content. Q. David Bowers: The earliest truly significant auction containing a run of high-grade early quarter eagles was that of the John K. Curtis Collection auctioned in New York City by Bangs, Merwin & Co. in June 1859. Most had this description, meaningless today: "Proof ¼ eagle or $2½ piece."
