Proof 2004-S Wisconsin Silver 25C Discovered with Obverse Die Crack

NGC grader Matt Tucker recently identified a previously unreported die crack on the Proof 2004-S Wisconsin Quarter, which runs from rim at approximately 4:00 on obverse into the devices.

Several other States Quarters are known with die cracks, most notably the prominent "Spiked Head" clashes which emerge from the rim at 6:00 on reverse. These, however, are usually encountered on clad coins. The appearance of such a crack on a silver proof coin is much less frequent. All modern proof coins displaying die cracks are scarce as they are often caught by the Mint's quality control. As a result of their scarcity, they are all considered collectible.
