We report results of substitution effect of Ag for Cu as a function of x (0.0≦x≦1.0) in high Tc superconductors, (Ba0.1La1.9)AgxCu1-xO4-y compounds. Transition temperatures increased with a small amount of Ag and are nearly constant in a wide composition range of x (0.05<x<0.6). No superconductivity above 4.2 K was observed for the sample of complete substitution of Ag;(Ba0.1La1.9)AgO4-y compound.
