Professional Gold & Silver Buy/Sell Appraisal in Manhattan

Our experts evaluate precious metals, coins, and estate jewelry with accuracy and discretion — giving you a clear understanding of your items’ true value before you sell, insure, or store them.
Why Accurate Appraisal Matters
Gold and silver prices change every day. Relying on outdated estimates or informal evaluations can lead to major discrepancies in value. A professional appraisal ensures your pieces are tested, documented, and valued according to the most current market data.
At Louis Martin Jewelers, every item is tested on-site to verify purity, weight, and overall condition. Whether you’re evaluating an heirloom collection, fine flatware, or gold jewelry, our goal is simple — to provide honest evaluations backed by decades of trust.

Our reputation has been built on trust and professionalism. After testing your items, we walk you through how purity, weight, and live market rates determine value.
