    "abstract": "We use the formulation of the quantum mechanics of first quantized\nKlein-Gordon fields given in the first of this series of papers to study\nrelativistic coherent states. In particular, we offer an explicit construction\nof coherent states for both charged and neutral (real) free Klein-Gordon fields\nas well as for charged fields interacting with a constant magnetic field. Our\nconstruction is free from the problems associated with charge-superselection\nrule that complicated the previous studies. We compute various physical\nquantities associated with our coherent states and present a detailed\ninvestigation of their classical (nonquantum) and nonrelativistic limits.",
