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.


Always a good experience here! Definitely the place in town I enjoy buying coins from, and I’d recommend them to anybody. Helpful staff, reasonable prices, and wide selection.

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”


Wonderful experience, Nick and Laura made it seamless and stress free. Thank you! They also sell super cool items!!

The staff are quick at work but not too quick to make you feel pressured into buying items or selling your items. They teach you about the items and tell you if they have use for your items or not. If they don’t have use for your items they call other places to see if they have a use for the items. Great staff!


Great family run store. I’m well taken care of every time I show up at this location. Thank you Nick.

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…

Grateful for the Nevada Coin and Jewelry shop, I just adore it. I took some collectable figurines in and they bought them. I came out smelling like a rose. You should’ve been there to see the big smile on my face. I ran all the way home to look for some more. Can’t wait to get back! I can sure use the money!


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.

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

My friend and I came here to sell some coins and jewelry. We first saw Scott about some coins. He was very friendly and knew his stuff. Afterwards, he brought us over to Sheila who looked at our jewelry. She was also very nice and professional. We will definitely come back here again. GREAT PLACE!!!!

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.
