  • 5 star review  Fairly priced, they did not gouge me and underpriced the value of what I had to offer. Jake was wonderful at assisting me and I WILL be returning to buy and sell on the future!

    5 star review  Nice place, nice service, knowledgeable staff. But they do have a very high markup, which is just happening in the silver industry now. I really do like the store, though.

    5 star review  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.

  • 5 star review  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.
