@Jpp I see you have asked about a few different cents after the 1993 transitional change with WAM/CAM. As @rickmp stated, study the differences. Besides just the distance of the A and M, there are other differences to help you with identifying it. One item may 'look' like one or the other, but it should have all the identifying areas. The designer initials next to the memorial, is one of the items I use. The WAM designer initials are closer to the memorial and the G has the serifs on the leg. You can also tell by the A in STATES. It will be centered, instead of closer to the second T. The CAM designer initials will be further away and the G leg will be straight without the serifs. The A in STATES will be closer to the second T. Another site on the subject. http://doubleddie.com/58348.html
Take a 1991 cent and a 1993 cent and spend a few moments studying AMERICA, paying particular attention to the ME on both. Give it a try and you'll understand my point.
