Was recommended to this place by a Cuban friend because I was nervous about selling family heirlooms from Cuba. (My mother smuggled them in her bra when Fidel took power). It was time to let go of our cherished 18k solid gold Jose Marti coins from the early 1900’s. I had gotten prices from other shops and this location offered the best price. I left feeling confident that it was a fair transaction. The representative (David) was kind and very understanding of the emotional component to this sale. Definitely will recommend to my family and friends.

Incredible and excellent company. I was looking for where to sell my Rolex and get a fair price for it. Of all the companies that I contacted, you predominated. I got a response right away (late at night and Sunday), they made me an instant offer (the best offer compared to rest I received from other 20 places on Monday) and recommended me to their local office. They have an incredible place, excellent service, a fairly simple and fast purchasing process. It was a pleasure doing business with you.
