It is commonly agreed that near-Earth objects (NEOs) can originate from the main asteroid belt, through dynamical resonances, or from the outer Solar System. Spectroscopic observations of NEOs and their taxonomic assessment can in general add useful hints on their origin. We present visible and near-infrared spectroscopy of 7 peculiar NEOs observed within the SINEO (Spectroscopic Investigation of Near-Earth Objects) survey, which have produced more then 100 NEOs spectra. Five of them result to be spectrally peculiar, belonging to the rare V and R classes. We describe their connection with possible parent bodies in the main belt. The other two objects have peculiar orbits being comet-like. Their spectroscopy gives a B- and X-type which is compatible with the scenario of being objects which originated in the outer Solar System.
