Authentic Indian Arrowhead Artifact Sherman & Gilliam Counties Or. Brown Marble

Description

My husband of 38 years past away a few years ago at the age of 82. He hunted for & collected arrowheads since he was a young man.
I am downsizing his collection.
I will try my best to describe any flaws, but I really do not know much about them.
Some of his arrowheads were pictured in Overstreet Identification  and Price Guide Book INDIAN ARROWHEADS by Robert M. Overstreet, Eighth Edition
This brown marbled colored artifact arrowhead is 1-5/8" long, 1/4 thick and 1" across.
Tip of edge near point is scraped. May have other damage.
The last  picture is the frame where this arrowhead  or artifact came from. The frame was  marked "Sherman, Gilliam County's Or."
The John Day River, between the 2 counties is a tributary to the Columbia River.
I hope my pictures will help you decide.
Please email me if you have any questions.
I do combine shipping.
