I had a good experience but after I got home and thought about it, I realized Mary took a commission on each piece I sold!!! And I sold 5 pieces. That could have been in my pocket! if I went to a different place like a pawn shop and received more money. Next time pawn shop for coins and gold. They don't take a commission on each piece.

Mary is an incredibly honest, kind and transparent person. She directed me elsewhere for an item I was selling in order to help me get the best bang for my buck which is very rare to see nowadays. I will be bringing some other items she had mentioned she takes, and letting others know of this gem of a spot. Thank you Mary!

Excellent and fun service. Mary was prompt and spent the time going through all my items and explaining the value of each item. After all my items were understood, I got a fair price and a check on the spot. There were a few items that she did not want and she provided a person to contact. Selling gold can be a mystery but not with Mary at Valley Goldmine. You will not walk way wondering if you were treated fairly- You will know it. I am sorry I can give her 10 stars

Valley gold mine is definetly the best place in Phoenix Scottsdale Tempe area to take your gold! Mary is fair and even shows you exactly how she gets her prices and does not try to rip you off at all compared to some other gold/pawn shops that turned out to be pretty sketchy experience after dealing with valley goldmine! Took my item back to Mary to sell! Appreciate her transparency when working with her and she’s incredibly nice too!! Highly reccomend!

I had the opportunity to work with Mary @ Valley Gold Mine on a once in a lifetime coin find. While searching through a suitcase of raw, circulated Morgan Silver Dollars with one of her customers, one date caught her eye. Soon I received a text from Mary asking, “the 1893-S Morgan is a better date, right?” I replied, “uh yea, it’s the key date!” I let her know that this date/mintmark is commonly counterfeited or more often altered (fraudsters will add an “S” to an 1893 Philadelphia coin, which has no mintmark), so I needed to see the piece in person to verify it exhibited authentic diagnostics. Upon viewing the coin, I was shocked to learn that it was authentic. Mary and I determined that we would send this rarity into PCGS, a top 3rd Party Grading Service, to get it professionally graded and slabbed. The coin came back Very Fine 35 (VF35), giving it a retail value of about $5,000. This was such a cool find. Something that almost never happens. The rare coins are rare for a reason – you don’t find them everywhere. The moral of the story though is that Mary showed unquestionable integrity with her customer. Where many dealers would have attempted to rip the customer off (buying this key date as a common $25 coin), she notified the customer of the find immediately and then worked diligently to maximize the customer’s value. Strong ethics; an honest business person. Bob DeLean DeLean Numismatics

I was very nervous about selling my gold. I found Valley Goldmine online and read some great reviews. I emailed about an appointment and Mary called me back in a few minutes. I set up an appointment that was convenient for me and went to her beautiful office. Mary was very knowledgeable and honest. I was shocked at how much money I made off of my broken and discarded gold. She was very honest about the amount of money my diamonds were worth and even had her jeweler take the diamond out of one of my rings and mailed the diamond back to me. I would definitely use Valley Goldmine & Mary again. Great experience!

I have never sold gold to anyone before and was a bit nervous because I didn't know who to trust. After reading all the amazing Google reviews for Valley Goldmine, I had no doubt that Mary was my go-to gal. She was so thorough in explaining how the entire process works and I felt like she was honest and forthright. I had no idea what I was going to get for my jewelry, but I was VERY happy when she told me what she was going to pay me. I HIGHLY recommend Valley Goldmine if you want to sell your gold and silver and know that you aren't getting ripped off.
