Pre-Columbian style earthenware artifact fragment

This small archaeological artifact fragment is crafted from a coarse, porous earthenware ceramic material showing earthy brown and tan tones. It exhibits an irregular, broken shape with heavily worn and weathered surfaces, typical of excavated ceramic material. The object rests in a hand for scale, appearing to be a few centimeters in length. A notable feature is hand-written ink markings on the flat surface, consisting of a fractional notation or catalog number reading '1 / 227' with an additional 'x' underneath, suggesting it was part of an unverified collection or inventory. The fragment displays visible wear, surface degradation, fractures, and loss of original features due to age and handling. There are no maker's marks or stamps directly molded into the ceramic. The owner attributes this object to the Mesoamerican San Juan Teotihuacan culture; however, this user-supplied attribution is entirely unverified and requires professional archaeological assessment. The style and material are broadly consistent with ancient pre-Columbian pottery shards, but authenticity and specific cultural origin remain unverified.

Based on what I can see in the provided image, this object is a small, weathered earthenware ceramic fragment displaying coarse porosity and handwritten catalog markings reading '1 / 227'. The owner identifies this as part of the Mesoamerican San Juan Teotihuacan culture. I cannot verify this cultural origin, age, or material composition from a photograph alone; physical inspection, scientific testing such as thermoluminescence, and context from a documented collection are required to evaluate such claims. Assuming the hypothetical attribution to ancient Pre-Columbian pottery is correct, small surface shards with heavy damage and loss of original features typically occupy a modest niche in the antiquities market, as demand is generally concentrated on intact, fully formed vessels or well-documented figural pieces. Market behavior for fragmented, unprovenanced study shards of this scale typically ranges from $50 to $150. If the item turns out to be a modern reproduction, replica, decorative copy, or made simply 'in the style of' ancient pottery, the value would drop significantly, likely reducing it to a nominal decorative or educational value of $10 to $25. A physical examination by a qualified specialist in Mesoamerican art and material culture would be necessary to fully understand its nature and potential context.
