This specimen is an isolated large mammalian canine tooth, identified as originating from a lion (Panthera leo). The tooth displays a curved, conical shape typical of predatory carnassials, with a smooth, polished enamel surface over the crown. The coloration is an aged creamy-white to light ivory yellow, consistent with natural maturation and the provided context of being 20 years old. In terms of construction, it is a biological hard tissue composed of dentin and enamel. The root section appears to be recessed or missing, showing a flat, slightly rough top where it likely separated from the gum line or jawbone. Notable features include the sharp apex and subtle longitudinal striations visible under close examination. Condition-wise, the tooth exhibits a natural patina with minor surface scratches and a small amount of residue at the base, but it remains structurally sound with no significant cracks or calcification loss. While there are no maker's marks, as it is a natural biological object, the high degree of preservation suggests it has been stored in a climate-controlled environment. Such items are often kept as part of natural history collections or as ethnographic curiosities.

I have carefully examined the provided images and descriptions of this biological specimen. The tooth exhibits the diagnostic conical curve, deep root-to-crown ratio, and longitudinal enamel striations characteristic of a Panthera leo (lion) maxillary or mandibular canine. The coloration suggests a natural patina consistent with a 20-year age claim, showing no signs of synthetic casting or bleached restoration. The structural integrity is excellent, with a sharp apex and minimal desiccation cracking, which often plagues older specimens. The market for ethical taxidermy and natural history remains stable, though strictly regulated. Values are driven by size and the absence of damage; specimens measuring over 3 inches are particularly desirable. Comparables for authenticated lion canines in similar preserved condition typically range from $400 to $700 depending on the specific diameter and weight. However, significant legal caveats apply. International trade is restricted under CITES Appendix II, and many jurisdictions require proof of legal harvest or pre-convention status. Without physical handling, I cannot definitively rule out highly skilled resin replicas or confirm if the internal pulp cavity shows natural mineral deposits. A full authentication would require a tactile density test, UV light exposure to check fluorescence (natural teeth fluoresce blue-white), and documentation proving the date of acquisition to ensure compliance with federal and international wildlife laws. Provided it is legally sourced, this is a high-grade specimen for a collector.
