How to Grade and Value Fossil Shark Teeth

A fossil shark tooth's value rarely comes down to size alone. This curator's guide covers the factors that actually drive grade and value: slant height measured correctly, completeness, enamel quality and color, serrations, tip and root condition, percent restoration, pathology, and locality. It explains a practical gift / collector / investment framing, why bigger isn't automatically better, why a disclosed repair is fine but a hidden one isn't, and how to read a listing and a COA.

How to Clean and Display Fossils the Right Way

A fossil shark tooth survives millions of years underground, then takes most of its damage on your shelf. This guide covers how to clean and display fossil shark teeth the right way: the gentle cleaning that helps, the acids and shortcuts that destroy value, the real enemies in a display case (UV, humidity swings, handling oils), how to stabilize flaky matrix, and how to label a specimen so its species, locality, and provenance endure.
