This past Saturday I had the opportunity to meet the owner and team at Nevada Coin and Jewelry. I didn’t know what to expect but they made me feel both comfortable and safe. I went through my collection of jewelry, both broken pieces and things I thought were of no value at all. They took the time to explain what each carat weight was worth and they helped me sort through my items. I was amazed at what they gave me for things I would never wear or use. I would recommend you stop in and speak to them, you might be as pleasantly surprised as I was.

Been living in Vegas for many years and never had to sell or hock any of my items unfortunately as luck would have it that day did eventually find me and let me tell you is it a tough racket to find a decent place out here to do business with. Pawn shops are a joke and could care less about their customers and treated me like another number. Tried and tried and place after place the numbers where all over the place. Finally decided to go to these guys and I’m glad I did. They tested each piece of my jewelry right in from of me with some kind of xray machine. They explained how they calculated the price and paid me cash on the spot. Avery was very helpful and didn’t mind answering my questions and explaining what they do. I left feeling I got the best price for my items. I would recommend them to anyone looking to sell their jewelry.

They took the time to help me sell my item and find an item. The staff does not rush you or pressure you into buying something. They take you on a little adventure by telling you about the items you are selling and looking at…

A.J. and Robert are so friendly and make it so you have the best deal with the items you bring them. They have so much knowledge about all the items they have in their shop and they like to teach others about what they know…


My wife cashed in some coins and we got top dollar. We have sold to others before but no more, we found a real professional store in Nevada Coin & Jewelry. “Thank You”


What inspired me to go to NV Coin and Jewelry was I was an ad on the TV for the shop. I was not too sure about going to NV Coin and Jewelry to sell my jewelry because I have been to many other pawn shops but haven’t found a good deal for my jewelry. After I went to Nevada Coin and Jewelry it was a big relief for me selling my jewelry for a good price.


A great selection of coins and other numismatic related material. Very professional.

Staff was friendly, knowledgeable, and responsive. Building had great security to helped me feel safe in handling my items.

After visiting a couple of the “traveling gold & silver merchants” who came to Mesquite, I made a call to Nevada Coin & Jewelry in Las Vegas… David was very helpful and professional. Their prices were the best I had seen… I left very satisfied with my trip and the deals we made. I will definitely go there again.

While vacationing in Las Vegas I did what a lot of people do I’m sure or at least that’s what I’m telling my wife ..I blew through the money I brought a little quicker than expected and I ended up having to shop my Rolex around to several dealers to save the trip. So I looked online for places, most offers over the phone were low and that’s if they would even quote me in the first place. I spoke to a guy at Nevada Coin and Jewelry who gave me a fair ball park price and a reasonable explanation as to why his number couldn’t be solid. Went down expecting to get the lower number and in fact Robert their Rolex expert said my Rolex was a better model then I had described. He paid me a higher number than he quoted. Thanks for saving my vacation guys.

I am a brazilian and had the chance to deal with Nevada Coin. I was there to sell some gold coins and they paid me the best price I could fetch in Las Vegas. They are professional, courteous and trustworthy. Before visiting their premises I got a tentative appraisal by phone which I found reasonable. In the shop the attendant offered to approach the manager to get me a (gasp) BETTER price. Do yourself a favor and don’t bother talking to their rude and unprofessional competitors. They will treat you like a moron and quote prices accordingly. For Nevada Coin, five Stars all the way.


Really cool cats over at Nevada Coin and Jewelry. You would’ve thought that I was “Madonna” the way those guys treated me. I was so mesmerized by all of the antiques, they have in there, I believe I was there for two hours, just looking, unbelieveable! When I went in I was so hot, they offered me a cold bottle of water, how cool is that? It felt like home to me. I wanted to get a price for some old jewelry that was passed down by grandma, I was well satisfied. When I left the shop, I was singing “Money, Money, Money.
