Few people know or value precious metals like Bob Campbell.
It’s no accident the metal connoisseur had two real copper metal garage doors made by Martin Door Manufacturing installed on his home.
The doors say almost as much about Campbell, as the other things he surrounds himself with.
The owner of “All About Coins” in Salt Lake City has made a living buying and selling rare coins. He has also published books and videos on the subject.
His retail store in the Sugar House area of Salt Lake City reflects his love of the rare and unique, from steel ceilings that date back to 1914, to collections of rare bottles and coins. His collection includes the largest collection of Pony Express medals in the country.
Campbell says technically copper is not classified as a precious metal, but its’ market value fluctuates like a precious metal. Like gold and silver, real copper metal has been a highly-sought after commodity for over 10,000 years. Highly serviceable as an electrical conductor, besides being beautiful, copper never rusts, 
but turns to a green patina with oxidation. Because of its waterproofing quality, copper was used heavily as a roofing material in ancient times.
The same qualities that make copper an enduring metal make it a perfect complement to use in a Martin Garage Door. Martin builds garage doors to last and uses architectural grade copper in every real copper metal garage door it builds.
In putting together a family museum in his home, Campbell thought copper would set the building apart. He put up copper flashing and then had Martin copper garage doors installed to complete the look. He is eager to see the doors continue to patina.
Campbell said his neighbors call his home “the castle.
That castle includes a turret behind the garage doors, where Campbell and his wife have built a showcase of the unique and rare. The enclosure includes special lighting and a floating staircase to create a one-of-a-kind environment for his precious things.
Campbell’s ability to prize copper goes beyond his garage doors and the trim on his home.
His most valued coin is a 1943 copper penny, which recently was valued at over $500,000. There were only 20 such coins minted in copper, by mistake that year. Because of the war effort in the U.S., the 1943 penny was issued in zinc-coated steel. One 1943 copper penny minted in the U.S. sold for $1.7 million in 2010.
Because of the value of scrap copper, Campbell said he worried initially someone might try and steal some of the flashing or copper used around the home.
A unique man, with a unique collection, Campbell is the youngest person to ever head the American Numismatists Association, a world-wide rare coin organization that dates back to 1891.
