Marg & Larry O’Neil: Welcome to the biggest cast iron collection on the planet

Marg and Larry O’Neil couldn’t have predicted just how far their love of cast iron would take them. The high school sweethearts have been married for 62 years and are former grocery store owners and real estate pros. In retirement, they decided to start collecting cast iron for fun — but things quickly got serious.

Today, the O’Neils have converted their home in Tacoma, Washington into what is affectionately known as the Cast Iron Museum — a home to antique, vintage, rare, and well-loved pieces of cast iron from across the world.

“We’ve got 13,000,” says Marg with a smile. “Give or take a few.” 

But like most great collections, theirs started simply enough. 

Larry says he bought his first piece in 1957 or 1958, for the simple reason that he needed a good skillet for cooking. “My mother used cast iron all the time,” he says. “She had three skillets hanging on the wall in the kitchen and I asked her for them, and she told me that my sister had already asked for them. I just decided if I wasn’t going to get hers, then I was going to go buy my own.”

Many thousands of pieces later, Larry and Marg’s collection includes cookware and so much more. “I just got involved in it and kept doing it,” Larry says.

The O’Neil collection includes many pieces of Lodge, from skillets to bakeware, that date back generations. Among the thousands of pieces in the museum are unique, decorative trivets — which take up an entire wall of gallery space; a colorful variety of enameled cast iron from across the rainbow and the world; skillets of all shapes, sizes and depths; big dutch ovens that have seen plenty of campfires; and even utensils and bottle openers.

“To be a good collector, you get a whole handful of marbles and you put them in your mouth. Then you walk around and you spit one out every once in a while. When you lose all your marbles then you become a good collector,” Larry laughs.
