The 1992 Philly close AM is listed as extremely rare. I can never tell if it is close or wide, but what's the other side of the coin? And the Denver one is good too.
This link ought to help you out. It’s all in the serif (or lack thereof) on the FG. https://www.errorvariety.com/Design/WAM-CAM.html @ldhair
Your coin is a WAM. The A in States is evenly spaced between the Ts. If it were a CAM the A would be closer to the T to its right.
