Guidance
Frequently asked questions
How quickly does Goldmine Exchange respond after I request a confidential quote?
Most inquiries receive an initial specialist reply within one to two business days, depending on photos, documentation, and complexity. Urgent timing can be discussed when you call our Deerfield Beach office.
What should I bring to an in-person jewelry or watch evaluation?
Bring the items, any grading reports or receipts you have, service records for timepieces, and a government-issued ID. Nothing is required for a preliminary photo review—we will tell you exactly what to pack before anything ships or travels.
Are valuables insured or protected while in your showroom or during shipping?
We use careful intake protocols and insured shipping options when items move between parties. Specific coverage details are confirmed with you before custody changes so expectations are clear in writing.
Do you serve clients outside Deerfield Beach, Florida?
Yes. Many clients start with a secure digital intake from across the state and beyond, then choose insured shipment or a scheduled visit. Local collectors also walk in at 204 N Federal Hwy.
Can I compare a collateral loan and an outright sale for the same piece?
Absolutely. We outline both paths with transparent assumptions so you can decide whether liquidity with redemption rights or a clean sale fits your goals.
Which asset classes do you specialize in besides fine jewelry?
Important watches, designer handbags, loose diamonds, estate collections, and—distinctively—select marine and aircraft collateral. Each category is evaluated using secondary-market reality, not generic scrap math.
