CAM'S and WAM'S heres the list of the ones you want to find: 1998-P (business strike) WAM (normal coin is a CAM) 1999-P (business strike) WAM (normal coin is a CAM) 2000-P (business strike) WAM (normal coin is a CAM) 1992-P (Business strike) CAM (normal coin is a WAM)----EXTREMLY valuable..a MS67RED just sold for $24,000.00 (Approx.5 coins known) 1992-D (Business strike) CAM (normal coin is a WAM)----Also EXTREMLY valuable....one just sold for $18,000.00 (Approx.15 coins known) 1998-S CAM (Proof) (normal coin is a WAM) 1999-S CAM (Proof) (normal coin is a WAM)
