Why us?

Welcome to The Gold & Coin Exchange (GCE)! We are celebrating this year as the largest and most successful coin and bullion dealer in Cobb County’s long and rich history. We have separated ourselves from the pack by creating an environment where our clients know they will be valued and that their pricing will be the best in the industry.

We ARE the LOCAL one-stop-shop precious metal industry professionals. Our faithful and prosperous client base has grown even during the current precious metal market downturn. Why you might ask? We have grown because we offer a multitude of services that run far deeper than simply purchasing your scrap metals. We have become a local leader in many other categories such as Diamond purchasing. We have direct relationships with the buyers in New York and Hong Kong which in turn allows us to offer unprecedented rates on loose diamonds and diamond jewelry! Also, we offer industry leading rates on gently worn Rolex, Patek Philippe, Ulysse Nardin, and Cartier timepieces.

Our goal is to serve the best clients with the highest levels of genuine, true, and tangible customer service which has been missing on many levels from our industry for numerous years. We aim to be the ONLY all inclusive Precious Metal, Rare Coin, Diamond, and Bullion Exchange in the Southeast United States. We aren’t afraid to divulge the industry secrets about pricing and prove to our competitors that we educate our customer base on the buying process rather than trying to price gouge and hope the customer accepts. This is not top tier customer service – this is the systematic hustling of hard working customers to increase their profit margin so dramatically that some shops are making 100-120% returns on their purchase prices. The secrets are out, and Gold & Coin Exchange will continue to revitalize the precious metals industry through our dedication to our clients, our community, and most importantly – our unwavering commitment to customer service that DEFINES customer service!

Welcome to The Gold & Coin Exchange in Marietta, GA – We look forward to earning your business!
