About Mary

Mary and her husband Erik were both working at IBM Microelectronics in Burlington, VT when they were blessed with a baby boy. Soon after, Erik took a job in Mesa, AZ and Mary left supply chain to go home and be a full-time mom. Like many families they worried about the rising cost of college education and when their son went into 1st grade, Mary needed to go back to work. But what could she possibly do that allowed her to pick up her son from school as well as continue to care for her mother-in-law who suffers from Alzheimer’s?
Erik was the one who came up with the answer, buy gold. Not like the typical pawn shop or gold buyer, buy gold in a safe, office environment by appointment only. This way not only would Mary be safe, but it would be flexible enough to accommodate her duties as a caregiver. She often refers to Valley Goldmine as her “mommy gig” and says that it was her “gold-bug” husband who got her into the industry.
It started out small and Mary learned the jewelry market as well as the precious metals market. Wanting her clients to get the most money for their jewelry, she would refer them to local jewelers if she thought they could get more that way. Sometimes they did and other times they returned to sell to Mary as the “melt price” she was offering was higher. Over time she learned what was in style and was able to better direct her clients to help them get the best price possible.
Now their son is in high-school and Mary continues to look out for her customers. Since so many people came to her with coins they had inherited, she found honest coin dealers who would pay well for collectible numismatic coins even if it is obvious that the seller doesn’t know what they have. Her motto, “If you do your best to help people, the rest will take care of itself.” is a testament to her success.

About Logan

Logan was in kindergarten when his parents purchased the Valley Goldmine franchise for his mother to run.  In the early days he would accompany her to some appointments, helping keep his grandmother busy watching shows on the iPad. (suffering from Alzheimer's, grandma was under Mary's care as well)  Now, 10 years later, he is a junior at Chandler high and actively helping the family business as the IT guy.
He helps mom with inputting data for the required police reports, website and google page posts, and has tried his hand at creating a separate Valley Goldmine website.  Logan aspires to study computer science, and the tuition is one of the main reasons his parents invested in Valley Goldmine. 

Testimonials

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.

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

COVID 19 UPDATE: Pursuant to Gov. Ducey’s Executive Order 2020-18, we are classified as an essential business . We have carefully considered the issues and have decided to remain open in order to be a safe option for those who are in need of funds in this tough time.

1 on 1 appointment = safe social distancing!  If you are looking for a little cash to get you through this tough time but leery of crowding at gold buyer & pawnshops, call us to make a private appt.

As a mother who also takes care of both Alzheimers & immuno-suppressed family members, safety is my primary concern.  Everything gets sanitized between every appt & I have a mask to wear while helping anyone with heightened risk or who would just feel more comfortable.

If you have old jewelry that you’ve been thinking of turning into cash, now may be the time.  The gold market is within ~10% of the historical highs, just be safe when you sell.
