I have searched $100 bills and no result was returned. AJR, AJS, AJT, AJV, AJU, AJW, AJY, BKD, BKG, EJA, EJC, EJE. Does anyone know the reason for those prefixes not returning results?

I have consecutive $100 UC. AJJ (3), AJJ (2), BJB (3), BJB (2), BJD (2), BJK (2), BJP (4), BJP (4), BKD (3). Are the values of these bills higher being consecutive numbers?
