Diagnostics for a Close AM include the M in AMERICA closer to the A than the E, the A in STATES closer to the right T than the left T, and the FG away from the Memorial. The NE in ONE on the west side vertical bar will have flared corners for the close. Diagnostics for a Wide AM include the M in AMERICA being midway between the A and the E, the A in STATES being midway between the 2 Ts, and the FG close to the Memorial. The NE in ONE on the west side vertical bar will not have flared corners (to the same degree as those on the Close AM). The appearance of how close the A is to the M varies as a function of die abrading and die deterioration. Therefore, confirmation of the attribution needs to be factored through the other two features. The distance between the A and the M is the least reliable diagnostic for WAM or CAM Here is a photo example by Ken Potter showing how spacing between letters may vary as a result of abrading.
