5/23/2019 Super friendly service & best of all always an honest opinion. Jack is always happy to see me if I am bringing in a small ticket item or a larger one for a price opinion. Appraisals are free. I have been pleasantly surprised how much some of my coins were worth and some old gold jewelry including my class ring & black hills gold.

5/24/2019 - If you’re looking to avoid the next recession by purchasing precious metals MinDak Gold Exchange is the place to go. Jack was very knowledgeable and knew what he was talking about, whether that was current market trends, news, future forecasts, etc.
