When you refer to amulets, do you mean decorative reckless like the ones women wear? If so that is probably not much of a problem as long as the one wearing them follow the proper ruling concerning adornments. Althought it is weird that a masjid would give those out as if it was a common shop.
If you refer to so called "magical amulets" those are completely forbidden in Islam. I would question any masjid that would get involved in such things. But make sure those amulets are really what you believe they are.
