New high-temperature and nontoxic superconductor families of Ag 1-xCuxBa2Can-lCunO2n+3-y witl~ Tc = 117 K and CuBa2Can-lCunO2n+4-y with Tc =116 K were discovered. These materials were prepared by the highpressure technique. The highest Tc was obtained for n=4 i.e. Agl-xCuxBa2Ca3Cu4Oll.y (Ag-1234) an
