    review rating 5  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.
