AI Appraisal Estimate

This artifact is a lithic multi-tool, identified as a hand axe and scraper, measuring approximately 3 inches by 2 inches. It is composed of high-quality chert, likely sourced locally in the Oklahoma region. The material displays a rich, butterscotch-to-tan coloration with deep ocher tones and visible crystalline inclusions typical of chert found in the Midwest. The tool features systematic unifacial and bifacial flaking along its primary edges, created through percussion and pressure flaking techniques characteristic of the Paleo Indian period. The construction demonstrates a clear 'bulb of percussion' on one face, indicating an intentional human modification of the stone core. Notable markings include several localized step-fractures and edge wear consistent with heavy use in scraping tasks and light hacking or wood-working. The surface exhibits a heavy desert varnish and a waxy patina, signifying significant age and long-term exposure to the elements before its discovery in Guthrie, OK. While there are some modern nicks on the sharper edges likely from field contact, the overall structural integrity of the piece is excellent, showcasing the durability of the selected material and the expert craftsmanship of its original creator. This piece represents a quintessential versatile tool from North America's earliest inhabitants, functioning as both a heavy-duty cutting implement and a skinning scraper.

Based on my examination of this Oklahoma chert multi-tool, I find it exhibits many diagnostic traits of a Paleo-Indian to Early Archaic lithic implement. The butterscotch patina and waxy surface luster suggest significant age and chemical weathering consistent with long-term soil burial. The 'bulb of percussion' and visible pressure flaking along the margins indicate intentional anthropogenic manufacture rather than geofact formation. The tool demonstrates classic versatility, with the thick core serving for chopping and the refined edges for scraping tasks. Current market demand for utilitarian Paleo-Indian lithics remains steady among regional collectors of Midwestern artifacts. While more aesthetically symmetrical points (like Clovis or Folsom) command thousands, expedient tools of this size and form typically range between $150 and $250 at auction. Several factors limit a higher valuation, specifically the modern nicks on the edge which detract from the 'as-found' condition. It is important to note that definitive authentication cannot be established through digital images alone. For a conclusive valuation, a microscopic analysis of the use-wear patterns (microwear) and a professional 'black light' test to check for modern tool marks or fresh surfaces would be required. Furthermore, established provenance—such as field notes or site maps from the Guthrie, OK discovery—is essential to verify its historical context. Without a certified COA (Certificate of Authenticity) from a recognized lithic expert, this appraisal represents an estimate based on visual proxies and assumed authenticity.
