Expertise: All U.S. coins 1792 to 1839, Liberty Seated and Barber Coinage.
Specialties: Finest Known Early American Coins, Condition Census Rarities

Joe O’Connor describes his life-long career in numismatics as “somewhat accidental”.

Over forty years later, Joe is still working at the temporary job he took in 1977, and Chicago has one less CPA.

It has often been said that, as numismatists, we stand upon the shoulders of those who have come before us. For Joe, those shoulders are many, but he credits his time working for Ed Milas at RARCOA during the 1990s, as the most influential period in his career. Joe’s approach to the market, his client relationships, and his love for the finest Early American coins are all an extension of the work he did at RARCOA.

For PCGS Coin Facts, Joe is a regular contributor to Early American coinage of all metals, 1792 through 1839, and Liberty Seated and Barber Silver, half dimes through half dollars, with a focus on the upper end of the condition census.

"When Greg was a 15 year old sophomore in high school (1977) his mom used to drive him to the Glendale coin show where he sold me Gem BU Mercury dimes, Walkers, and silver dollars he had bought around town. Then I watched him become a significant buyer/market-maker for dollars and Walkers. In the 1990's, he graduated to Ultra Rarities and bought and sold 1913 Liberty nickels, 1804 dollars, etc. Today, I believe he buys and sells (though his several dominant companies) more U.S. coins than any other person/firm in this country. I have been somewhat of a mentor to him, giving him advice along the way, and doing a ton of business with him. Now I ask him for advice. The student has become the master!"
