The need for a reassessment of nuclear magnetic dipole moments is prompted by recent experiments on the ground-state hyperfine structure in highly charged hydrogenlike systems which are sufficiently sensitive to probe QED effects. This work gives an overview of the magnetic dipole moments for the nuclei of interest, i.e., ${}^{165}\mathrm{Ho},$ ${}^{185,187}\mathrm{Re},$ ${}^{203,205}\mathrm{Tl},$ ${}^{207}\mathrm{Pb},$ and ${}^{209}\mathrm{Bi}.$ It is found that the present uncertainties in the nuclear magnetic dipole moment limit the interpretation of the accurate experimental hyperfine structures for these systems.
