PR034 Rare Clovis: Over 4" and made of a very extraordinary material. Dwain Rogers Certificate of Authenticity says material is Translucent Agate or Chalcedony. This material reminds me of the pearl looking snaps that you see on many old western style shirts. This Clovis point was part of the late Charley Sheweys Collection. It is pictured in Who's Who # 7 on page 173 in the lower left picture. This Clovis measures 4 1/16" x 1 1/8" and was recovered in South Central Montana.
