1999 Delaware State Quarter (Severely Corroded)

This item is a 1999 United States Delaware State Quarter, featuring the reverse design of Caesar Rodney on horseback. The coin measures approximately 24.26 mm in diameter and was originally composed of a copper-nickel clad over a pure copper core. However, the physical condition is severely compromised. The entire surface exhibits deep, dark grey and blackish oxidation, likely due to environmental damage or exposure to harsh chemicals/moisture (corrosion). The high points of the design, including Rodney's figure and the horse, show significant wear and flattening. While the user identifies this as a 'misprint,' the visual evidence suggests 'Post-Mint Damage' (PMD) rather than a mint error. The mushy appearance of the inscriptions including 'DELAWARE' and '1787' is characteristic of acid etching or extreme environmental exposure rather than a die error. There are no clear markings of a mint error like a clipped planchet or off-center strike; instead, the rim appears uneven from wear and physical abrasion. The coin lacks any original mint luster and displays a matte, pitted texture across both the fields and the relief elements.
