Variable thickness face plate for a golf club head

A golf club head comprising:

• a body having a crown portion, a sole portion, a toe portion, a heel portion, and a rear portion defining an inner cavity;
• a face plate comprising:
• a front surface;
• a rear surface;
• a face plate total surface area;
• a geometric center defining the origin of a coordinate system comprising:
• a horizontal or x axis parallel to a ground plane when the club head is at an address position, extending from near the heel portion to near the toe portion;
• and
• a vertical or y axis extending from near the crown portion to near the sole portion, perpendicular to the horizontal axis or x axis dividing the front surface into quadrants;
• a thickness measured between the front surface and the rear surface;
• wherein the thickness varies at different locations across the face plate to define a variable thickness profile, the variable thickness profile comprising:
• a peripheral region comprising a minimum thickness of the face plate;
• a transition region;
• and
• a central region comprising a maximum thickness of the face plate, the central region having an egg shape with a major axis that extends at a first angle between 2 degrees and 60 degrees from the vertical axis along a maximum length of the central region, and a minor axis extending along a maximum width of the central region;
• wherein the central region is asymmetric about the major axis and minor axis,
• wherein the central region further comprises a first side and a second side, wherein:
• the first side and the second side are separated by the minor axis of the central region;
• the first side is located between the minor axis and the toe portion;
• the second side is located between the minor axis and the heel portion;
• and
• a ratio measured as a surface area of the first side of the central portion to the surface area of the second side of the central portion is in a range between 1.0 to 2.0;
• wherein the horizontal axis and vertical axis divide the face plate such that the face plate comprises an upper heel-side quadrant, an upper toe-side quadrant, a lower heel-side quadrant, and a lower toe-side quadrant, wherein a greater percentage of a total surface area of the central region is located in the upper toe-side quadrant than in one or more of the lower heel-side quadrant, the upper heel-side quadrant, and the lower toe-side quadrant;
• wherein an intersection of the major axis and the minor axis define a center of the central region.
