Teryllium Newport (1997 Masters, Gen 1)

This is the first-generation Teryllium Newport, the black-finished version carrying a flush Teryllium insert and a TeI3 stamp on the sole. Drivingrangeheroes.com reports that this particular head is lacking the white elastomer ring around the edge that later Teryllium Newports would carry, and that its insert reads as copper-colored against the black finish.

The record on this one is defined almost entirely by the moment it's tied to. Drivingrangeheroes.com describes it as the putter used in Tiger's maiden Major win at the 1997 Masters, pointing to a TeI with no face stamping and no elastomer around the face seen in pictures of him on ANGC in his Sunday red. That association, if it holds, is what separates this head from the rest of the Teryllium Newport run rather than any change in milling or shape.

Drivingrangeheroes.com puts the range at $150 to $200. Set against later Teryllium Newports that picked up the elastomer ring, this Gen 1 head reads as the plainer, earlier build, its case resting on the sole stamp, the insert color, and the absence of the ring rather than on any documented spec change.
