Precious Metal Processing Company

Welcome to Precious Metal Processing Company

Since 1989, our family-owned business has specialized in recycling precious metal scrap, including dental materials, quality gold and platinum jewelry, and items containing at least 20% precious metals. With our simple mail-in process, competitive pricing, and three generations of family leadership, we make it easy to convert your unwanted precious metals into cash. We provide free shipping materials, no-obligation estimates, and prompt payment—all delivered with the traditional customer service values that have kept our customers returning for over 35 years.

Our Legacy

Precious Metal Processing Company was founded by Howard Greinetz in 1989. 

Mr. Greinetz served in the 55th Armored Infantry Battalion of the United States Army during World War II. He fought in the Battle of the Bulge and helped liberate Mauthausen concentration camp. 

After returning home from the battlefield, Mr. Greinetz committed his life to many philanthropic missions to help the Denver community as well as oppressed people abroad. 

Precious Metal Processing is now run by Howard Greinetz’s daughter, Teri Greinetz, and her children, Sean and Lisa Carnahan, who aspire to honor Mr. Greinetz’s legacy by continuing his business with the same integrity he modeled so well.

Many of our customers have been with us for decades because we provide competitive pricing and the traditional customer service that seems to be disappearing from too many businesses nowadays.  With all the gold buyers popping up these days, it is difficult to know who to trust and how to get the best price.  To help ease that uncertainty, we offer free estimates with no pressure to sell.  We want you to be informed and feel comfortable working with us.

Please give us a chance today and find out why we are still running strong after 35 years!
