My grandfather, W. Reid McKee (born and raised in Mt. Sterling, Montgomery County, KY) at one time owned the second largest Civil War collection. He co-wrote a couple of books on Civil War projectiles. My mother, his only child, only keep a few items and has decided to possibly sell some. There are two what I believe to be Native American Grooved Axes. However, having no knowledge on this the artifacts nor time period, can anyone share any insight about them?
