An item may be reviewed through one or more potential secondary market routes. Finding the correct route matters as much as the material itself:
How we match property to its highest-yielding secondary market:
Wearable, signed, branded, antique, or vintage jewelry and watches evaluated as finished pieces.
Recognized maison references, rare configurations, period jewelry, or collectible coins.
Loose or mounted diamonds and certified colored gemstones evaluated on 4Cs, origin, and treatment.
Recognized sovereign coins, hallmark-stamped bars, and rounds valued for fine precious metal content.
Coins affected by date, mint mark, variety, certified grade, rarity, and collector demand.
Recoverable accent stones, watch movements, findings, clasps, links, and reusable elements.
Broken, worn, or unbranded items primarily valued on exact gold, platinum, or silver weight and assay.
Condition alters review scope but does not make an item ineligible:
Reviewed for stones, metal, maker, components, and repair implications.
Reviewed for model, caliber movement, parts originality, service history, and repair risk.
Reviewed for remaining stone quality, metal setting, component value, and matching potential.
Reviewed for product identity, metal assay, authenticity risk, condition, and market route.
Reviewed for remaining weight, recut potential, jewelry context, and structural condition.
Choose ‘Not sure’ on the evaluation form and describe the object in ordinary language. Include visible marks, approximate size, condition, and a few clear photographs.

The core categories are precious metals, coins and bullion, diamonds, colored gemstones, fine and estate jewelry, signed jewelry and luxury watches. Eligibility and offers remain item-specific.
The team may review a single item, a matched set or a larger collection. Call before bringing a large, heavy, fragile or high-value holding.
Many broken or incomplete items can be reviewed for stones, metal, maker, components, repair implications and market route. Damage can affect value but does not automatically make an item ineligible.
Not always. Documentation can help with identification, completeness and research, but the physical item remains central. A box or receipt does not prove authenticity by itself.
Eligible unbranded jewelry may be considered based on precious metal, diamonds, gemstones, design, craftsmanship, period, condition and marketability.
Some laboratory-grown categories have dedicated or conditional policies. The material must be disclosed clearly and should never be represented as natural.
Eligible watches may be reviewed without box and papers. Reference, configuration, movement, originality, condition, service history and current demand still matter.
Some coins may have collector, date, mint, variety, grade, certification or set value beyond metal content. Every coin should be screened before a metal-only route is chosen.
Surface-plated items are not equivalent to solid precious metal. Eligibility depends on the item, maker, complete-piece market and active purchasing scope.
Photographs can help route an inquiry, but they cannot conclusively establish authenticity, metal content, gemstone identity, treatment, grade or a binding offer.
The lists are representative rather than exhaustive. Use the general evaluation form for an item within the confirmed categories, or call before transporting unusual material.
The What We Buy page does not include those categories. The current safe-default purchasing scope is precious metals, coins and bullion, diamonds, gemstones, fine jewelry and luxury watches.
Yes. A purchase evaluation is free and carries no obligation to accept an offer. It is not automatically a formal written appraisal, official authentication or laboratory report.
No. Buyers of NYC decides whether an item fits its active purchasing scope and market. The team may decline an item or recommend a different next step.
