I’ve been going through my change looking for errors and found this 1999-P Pennsylvania quarter that seems noticeably different from all my others. Things I noticed: Weight is 5.864g Most of my other quarters weigh between 5.62g–5.71g Rim/border is noticeably more raised than my other quarters Coin looks much shinier and more reflective/proof-like Very little visible copper on the edge compared to normal quarters When dropped next to a normal quarter it has a noticeably higher-pitched ring Details appear sharper/crisper than my other quarters The overall thickness seems close to normal, but the raised rim makes it feel thicker in hand. I included comparison photos with normal quarters. Curious whether this looks like a strong strike/proof-like circulation strike, plating, or some kind of mint anomaly.
