1. A golf club head, having a coefficient of restitution measuring at least about 0.80, comprising:

  • a body having a toe portion, a heel portion, a sole portion, and a crown portion, together defining a front opening;

    a striking plate disposed at the opening, the striking plate having a substantially planar striking surface on a front side, a rear surface on a rear side, and a periphery for attachment at the opening on the body;

    wherein the periphery has a top edge, a bottom edge, a first side edge, and a second side edge, and each point on the striking plate has a thickness;

    wherein the striking surface has a balance point at a central region and further has a total area on its front side;

    wherein the striking plate has a first thickness profile between the balance point and the top edge, a second thickness profile between the balance point and the bottom edge, a third thickness profile between the balance point and the first side edge, and a fourth thickness profile between the balance point and the second side edge;

    wherein the first, second, third, and fourth thickness profiles have thickness values at first locations encompassing the periphery of the striking plate and include minimum values adjacent the edges;

    wherein the first, second, third, and fourth thickness profiles have thickness values at second locations positioned between the first locations and the balance point, and third locations positioned in the central region between the second locations and the balance point;

    wherein the third and fourth thickness profiles having thickness values at least 1.5 times the minimum values at the second locations and include points having maximum values;

    wherein the first and second thickness profiles having thickness values at the second locations that are less than the maximum values of the third and fourth thickness profiles at the second locations, but greater than the minimum values of the first, second, third, and fourth thickness profiles at the first locations;

    and wherein the first, second, third, and fourth thickness profiles have thickness values at the third locations in the central region that are less than the maximum values of the third and fourth thickness profiles at the second locations but greater than the minimum values of the first, second, third, and fourth thickness profiles at the first locations.
