  In this work, we construct different classes of coherent states related to a
quantum system, recently studied in [1], of an electron moving in a plane in
uniform external magnetic and electric fields which possesses both discrete and
continuous spectra. The eigenfunctions are realized as an orthonormal basis of
a suitable Hilbert space appropriate for building the related coherent states.
These latter are achieved in the context where we consider both spectra purely
discrete obeying the criteria that a family of coherent states must satisfies.
