Ancient Obsidian Sacrificial Blade 3 1/4 inch California Collection For Sale

Purchased this in a California collection years ago, had many obsidian darts, this has stockton curve similarities, serrations, supposedly this was dug up in a mound in california but I believe it is mayan in origin.
Anyway, this is an ancient relic, some collectors don't care about origin, they just want a cool artifact, so go figure.
