Just going through the change in my pocket today and found this odd marking on a quarter where the mint mark usually is. At first it just looked like a dot but I believe it's a Denver marking that wasn't fully marked? Was just curious what it may be since I'm not even close to a coin expert and my curiosity got the best of me. Thanks!
Denver mint mark. The die fill with grease or a hard contact hit on the mint mark to alter the coin. 25 cents
