How to Vet Wholesale Coin and Bullion Suppliers: A Dealer's Checklist

The supply chain is the foundation of a reselling business. You can have the best Whatnot show format in the world, a polished eBay store, and a loyal TikTok following — none of it matters if your supplier ships you 0.925 silver labeled as .999, low-weights your bars, or disappears with a wire transfer. The coin and bullion category attracts fraud at both the retail and wholesale level, and the damage from one bad supplier relationship compounds: you lose money, your customers potentially receive misrepresented product, and your reputation on every channel you sell on takes the hit.

This guide is a practical vetting checklist for evaluating wholesale coin and bullion suppliers before you commit capital. It covers the due diligence process, the questions to ask, the red flags to walk away from, and how to structure your first orders to test a relationship before scaling it.

The foundational question: can this supplier be verified?

Before you evaluate pricing or product selection, verify that the supplier is a real, established business with a physical presence and a track record you can check.

Physical address: A real wholesale dealer has a real address — not a PO box, not a residential address with no business history. Look up the address. Does it match what you would expect? Is it listed on their website, their invoices, and their registration?

Business registration: Most states have a publicly searchable business registration database. Confirm the business name is registered, in good standing, and has been operating for more than a few months.

Online history: Run the business name through Google and look at the full result: their website, third-party reviews (Google Business, Trustpilot, BBB), forum mentions in coin communities, and social media presence. A legitimate wholesale dealer will have a searchable history. A brand-new presence with no reviews and no forum mentions deserves significant caution.

Industry affiliations: Membership in the Professional Numismatists Guild (PNG), the American Numismatic Association (ANA), or the Industry Council for Tangible Assets (ICTA) does not guarantee quality but does indicate an established operator willing to be accountable to industry standards. Ask for membership details and verify them independently.

Product authenticity and quality control

The single most important evaluation criterion for any bullion supplier is whether their product is exactly what they say it is.

What to ask

• What assay or quality control process do they use for incoming and outgoing product?
• Do they test all product or spot-test by lot?
• What is their process for handling an authenticity discrepancy?
• Have they had product authenticity failures? How were they resolved?
• What guarantee do they offer if a piece you purchase is found to be non-conforming?

Testing on receipt

For your first order from any new supplier, invest in testing:

Weight testing: A digital scale accurate to 0.01g lets you verify every piece. A 1 oz .999 silver round should weigh 31.10 grams (troy ounce) within manufacturing tolerance (typically ±0.05g). Consistent underweight across multiple pieces is a serious problem.

Sigma Metalytics or XRF testing: A Sigma Metalytics precious metals verifier or an X-ray fluorescence (XRF) analyzer tests surface and subsurface metal composition non-destructively. These devices are the professional standard for authenticity verification. If you are doing significant volume, owning one is worth the investment.

Acid testing: Acid testing is a lower-cost option for spot-checking silver and gold. It is less precise than XRF but can identify obvious fakes.

Physical inspection: Diameter and thickness within tolerance (spec sheets from known mints list these for standard products), edge characteristics matching known genuine examples, die details and strike quality consistent with claimed product.

Who guarantees what

Ask the supplier explicitly: if a piece I receive tests as non-conforming (wrong purity, wrong weight), what is your policy? A quality wholesale supplier stands behind their product with a clear replacement or refund guarantee for authenticity failures. A supplier who hedges on this question is telling you something important.

Pricing transparency and market alignment

Wholesale pricing for precious metals should be transparent and explainable. Premium above spot is the primary pricing variable — understand what you are paying and why.

Red flags in pricing

Dramatically below-market pricing: Gold and silver do not sell at large discounts below spot from a legitimate wholesale channel. If a supplier is offering product at 5–10% below what every other wholesaler charges for the same item, there is a reason. The most common reasons are counterfeit product, off-weight pieces, misrepresented purity, or a scam. Walk away.

Prices that “must be confirmed by phone”: Legitimate wholesale dealers publish their pricing (or share it readily upon account approval). Requiring phone confirmation for pricing, especially before you have any relationship, is either a high-pressure sales tactic or an attempt to qualify marks.

Vague or floating spot references: Premium over spot should be clearly stated. A supplier whose premium changes unexpectedly between quote and invoice, or whose “spot” reference is not verifiable against standard market sources (Kitco, APMEX spot, LBMA), is not operating transparently.

Tiered pricing structure

Evaluate how pricing tiers work. The standard structure rewards volume:

• What are the tier thresholds? (Units, dollar amount, annual spend?)
• Are tiers applied per-SKU or per-order total?
• Are tiered discounts visible before you order, or do they require negotiation?
• Is there a loyalty tier for long-term accounts?

Understanding the pricing structure before your first order tells you what your economics look like at current volume and what they could look like as you scale.

Shipping and logistics reliability

Shipping is where supplier relationships most often fail in practice, even when the product itself is fine.

What to evaluate

Carrier and insurance policy: Legitimate wholesale bullion shipments travel insured for full replacement value. Ask specifically: what carrier do you use, what is the insurance coverage included in your standard shipping, and what is your process for a lost or damaged shipment?

Declared value practices: Some suppliers ship high-value parcels with low declared values to reduce carrier costs. This saves them money but leaves your shipment under-insured if something goes wrong. Confirm the declared value on your invoice matches the insured value on the shipment.

Tracking: Every wholesale bullion shipment should ship with a tracking number provided to you at the time of shipment. Same-day or next-business-day tracking provision is the standard.

Lead times: What is the realistic ship time from order to departure from their facility? How long does transit take? Are lead times affected by spot market volatility (a surge in demand can slow processing)? Understanding realistic lead times lets you plan your inventory cycles and avoid going out of stock between shows.

Handling for high-value shipments: For orders above a certain threshold, additional protections (signature confirmation, direct carrier delivery, no mailbox drop) matter. Does the supplier apply these automatically or do you need to request them?

Test the shipping experience

On your first order, note: when did they confirm the order, when did they ship it, was the tracking accurate, how was the product packaged, and did it arrive undamaged? A supplier who delays shipment notifications, provides inaccurate tracking, or packs product inadequately is one you will have problems with at scale.

Communication and account support

A supplier who is difficult to reach when you have a question is a liability that compounds with order volume.

Response time: Send an inquiry before you open an account. How quickly do they respond? Is the response helpful and specific, or generic? Response time before the sale is often the best predictor of response time after a problem.

Proactive communication: Does the supplier notify you when your product has shipped? Do they flag delays before you have to ask? Do they alert you to upcoming releases or inventory changes? Proactive communication means you can plan around their operations.

Account management: For serious wholesale accounts, having a specific point of contact — someone who knows your account history and can resolve problems directly — is worth asking for explicitly. Many established dealers assign account managers at certain volume thresholds.

References and community reputation

No due diligence checklist replaces direct feedback from other resellers who have bought from a supplier.

Ask in reseller communities: Facebook coin groups, the Whatnot seller community, eBay seller forums, and the r/Silverbugs / r/WhatNot communities all include active resellers who will share their supplier experiences honestly. Post a direct question: “Has anyone used [supplier] for wholesale? What was your experience?”

Request trade references: Ask the supplier for two or three reseller references — other accounts who buy from them regularly and can speak to the experience. A supplier who cannot or will not provide references is telling you something.

Check complaint history: The Better Business Bureau, Google Reviews, and Trustpilot are imperfect but useful. A pattern of unresolved complaints about shipping, authenticity, or communication is a hard signal to ignore. A few negative reviews among hundreds of positives is normal; a high complaint rate or recurring themes is not.

Structuring your first orders

Even a supplier who passes all the above checks should earn your full trust incrementally rather than receiving a large first order.

Start small: Place a test order at a volume that lets you evaluate product, shipping, and invoicing accurately without significant capital at risk. Something in the range of 10–25 pieces is often right for a first order.

Evaluate everything: Weight-test several pieces, inspect condition against description, time the shipping, review the invoice for accuracy, and document the entire experience.

Scale deliberately: If the test order is clean, place a second order that is 2–3x larger. Evaluate again. If that goes well, you have the beginning of a real supplier relationship you can scale with confidence.

Diversify: Even after you have established relationships with one or two reliable suppliers, maintain a backup option. Supply disruptions, business closures, and inventory gaps are real. A single-source supply chain is a fragility.

What to look for in a long-term supplier partner

The best wholesale relationships are built on mutual interest in the other’s success. A supplier who wants to understand your sales channels, who brings you new product that matches your customer base, who gives you early access to releases, and who improves their service based on your feedback is a partner. A supplier who treats you as an anonymous purchase order is a vendor.

We have structured our wholesale program around the former. We want to know what you sell, where you sell it, and how to make our product work for your shows and channels. Exclusive designs, tiered pricing that improves as your volume grows, and pre-order access to upcoming releases are how we make that partnership tangible.
