Systematics in the superconducting behavior of $Ln_{2-x}Sr_x(Ba_x)CuO_4$, $La_{2-x}Sr_{x-y}Ba_y(Ca_y)CuO_4$, ${(La_{1-x}Ln_x)}_{2-y}Sr_y(Ba_y)CuO_4$ with Ln = Pr, Nd or Y and related systems are presented. The role of stoichiometry and lattice parameters of these mixed valent Copper oxides is indicated. These high $T_c$ superconducting oxides exhibit high-temperature resistivities in the borderline of the metal-nonmetal transition.
