Modern US quarter piece, stylistically consistent with the New Jersey statehood design

This appears to be a circular metallic coin or token, bearing imagery and text consistent with the reverse side of the United States New Jersey statehood quarter. The visible markings include 'NEW JERSEY' and the date '1787' at the top, along with a central relief depiction of General George Washington crossing the Delaware River. Below the image, the text 'CROSSROADS OF THE REVOLUTION' is partially legible. The object exhibits a dark, possibly aged or corroded surface with an uneven patina, appearing brownish or bronze-like in this lighting, though the standard circulation issue is a copper-nickel clad composition. There are visible signs of wear, surface pitting, and potential oxidation throughout the relief. Without physical inspection, it is impossible to determine if this is a standard circulation coin, a proof striking, or an aftermarket plated version. The design is based on the 1999 New Jersey state quarter series. Identification as a US Mint product is a hypothesis based on standard numismatic designs and remains unverified as weight, edge reeding, and the obverse side are not visible for inspection.

Based on the provided imagery, the object exhibits visual characteristics consistent with the reverse of a 1999 New Jersey state quarter. My evaluation is based on the hypothesis that this is a circulation-strike United States Mint product; however, I cannot verify the weight, edge reeding, or obverse imagery from a photograph alone. The surface displays significant dark discoloration, pitting, and oxidation which appears to deviate from a standard copper-nickel clad appearance. While this could suggest environmental damage, it might also indicate an aftermarket plating or a non-mint casting. Because I cannot physically inspect the piece, I cannot determine if the patina is superficial or if the base metal differs from standard specifications. In the general numismatic market, common-date state quarters in circulated or damaged condition typically trade at their face value of $0.25. If the item were a recognized mint error, the value would be higher, but based on what I can see, the surface issues appear to be post-mint damage. If this item were determined to be a non-precious-metal replica or a contemporary copy, its market value would be negligible. To form a more precise conclusion, an in-person examination by a professional numismatist would be required to verify the metal composition, check for a 'P', 'D', or 'S' mint mark on the obverse, and ensure the weight aligns with official mint standards of 5.67 grams. Without such authentication, the item should be valued as a standard circulated coin.
