Great American Coin Company (GACC) has been selling gold, silver, platinum, and collectible currency online since 2006.

If you've searched for a place to buy bullion or add to a banknote collection, you've probably seen their name come up alongside APMEX, JM Bullion, and a dozen smaller regional dealers.

This review looks at what they sell, what they charge relative to spot price, and what actual customers say about ordering from them.

Key Takeaways

• Great American Coin Company charges a premium of roughly 20% over spot on gold eagles and nearly 48% over spot on silver eagles, based on pricing pulled from their site on July 30, 2026.
• The company is not BBB accredited and holds a "Not Rated" status with the Better Business Bureau, though it has been in business since 2006.
• Customer sentiment is mixed: a 4.5-star Yelp rating sits next to Trustpilot complaints about slow shipping and pricing, while the company says it hasn't actively managed its Trustpilot account since 2018.

Company Background

Gary Dyner founded the Great American Coin Company in 2006 out of Los Angeles. His son Stephen Dyner joined the business in 2010, bringing a marketing and management background to the operation.

The company now operates as Great American Coin Group LLC, based at 11301 W Olympic Blvd in Los Angeles, and lists itself as an American Numismatic Association member and an authorized reseller for NGC and PMG grading services.

That last part matters if you're buying graded coins, since it means the coins they sell with third-party grading come from legitimate certification services rather than in-house claims.

One small wrinkle worth flagging: the BBB profile lists a business start date of October 10, 2009, while the company's own site says it launched in 2006.

It's not a huge discrepancy, but if you're the type of buyer who cross-checks everything before wiring money for a five-figure gold order, it's the kind of detail that's easy to notice.

What They Sell

GACC's catalog is bigger than most people expect from a mid-sized dealer. Their inventory breaks down into a few major categories:

That banknote and paper money selection is actually where GACC differentiates itself. Plenty of bullion dealers sell Eagles and bars.

Fewer stock a "Trillion Set" of Zimbabwe hyperinflation notes or complete runs of 1929 Federal Reserve Notes. If you're a currency collector rather than a straight bullion investor, this is one of the more specialized catalogs you'll find.

Pricing: How GACC Stacks Up Against Spot

Precious metals pricing is where most reviews go vague, so here's actual data pulled directly from GACC's product pages on July 30, 2026, compared against spot prices from the same day (gold at $4,080.76/oz, silver at $58.10/oz, per Trading Economics).

Gold at a 20% premium is on the higher side for a one-ounce government coin, though Eagles typically carry more markup than generic bars because of mint sourcing costs and the coin's legal tender status.

The silver premium is the number that stands out. A 48% markup on a single silver Eagle is steep even accounting for the fact that fractional and single-unit silver products almost always cost more per ounce than bulk purchases.

If you're buying silver specifically to track spot price movement, a single coin at nearly 1.5x spot eats into your upside fast.

Larger orders and bulk silver bags bring the per-unit premium down, so the math changes if you're buying in volume. Still, worth comparing before you check out.

Reputation: What the Review Sites Actually Show

Here's where things get interesting, because different platforms tell different stories.

The Better Business Bureau lists Great American Coin Group LLC as "Not Rated," meaning the BBB doesn't have sufficient information to issue a grade, and the company is not accredited.

Being unaccredited isn't automatically a red flag (plenty of legitimate small businesses skip BBB accreditation because of the membership fee), but it does mean you're not getting BBB's dispute-resolution backstop if something goes wrong.

On Yelp, the company holds a 4.5-star rating, described by reviewers as a mix of positive and negative experiences, with recurring complaints centered on pricing, shipping speed, and customer service response time.

Trustpilot reviews are more scattered. One customer reported never receiving an order and noted that many of the five-star reviews came from accounts that had only ever reviewed this one company, a pattern that can suggest incentivized reviews.

In a response posted to that review, the company stated it has not actively managed its Trustpilot account since September 2018 and does not solicit reviews from customers, adding that it completes hundreds of orders per day with a low complaint rate.

On the company's own site, testimonials from customers like Ralph Anderson and Jane Sauls describe fast international shipping, accurate order fulfillment, and responsive customer service, particularly for currency purchases like Vietnamese dong and Iraqi dinar.

Put together: this isn't a company with a spotless record, but it's also not showing the kind of pattern (mass unresolved complaints, license revocations, criminal actions) that would put it in scam territory.

It reads like a mid-sized family business with normal operational hiccups and an under-managed online reputation presence.

Ordering, Shipping, and Payment

A few operational details worth knowing before you buy:

Frequently Asked Questions

Is Great American Coin Company legitimate?
Yes, it's a registered business that has operated since at least 2009 (per BBB records) or 2006 (per company records), with a physical office in Los Angeles and NGC/PMG authorized reseller status. It is not BBB accredited.

Does Great American Coin Company charge more than spot price?
Yes. Based on July 2026 pricing, gold Eagles carried roughly a 20% premium over spot and silver Eagles carried closer to 48%, both higher than what large-volume bullion dealers typically charge on the same products.

What makes this company different from other bullion dealers?
Its international banknote catalog, especially Zimbabwe, Iraqi, and Venezuelan currency, is deeper than what most gold and silver dealers stock.

Is customer service reliable?
Reviews are mixed. Yelp shows a 4.5-star average, but shipping delays and slow tracking updates come up as recurring complaints across platforms.

Who This Company Fits

If you're a currency collector chasing Zimbabwe trillion notes or old Federal Reserve gold certificates, GACC's catalog is genuinely hard to match.

If you're a bullion investor buying gold or silver purely to track spot price with minimal markup, the premiums here run higher than what you'd pay at a large-volume dealer, and that gap matters more the bigger your order gets.
