About Us

Our Business

Coin Rarities Online is a full service internet and mail order coin company owned by John Agre.

We buy, sell and trade rare coins and related items on a retail and wholesale basis and provide numismatic services to our clients.  We attend major coin shows and coin auctions around the country and, sometimes, around the world.  We are members of major numismatic organizations and clubs.

It's pretty simple, really.

Our Philosophy

Our business philosophy is not very complicated either:

We believe in absolute honesty and integrity in all of our dealings.

We believe it is our responsibility to add value for our clients, and we hope that if we do that we can earn a fair return for ourselves.

We believe in research and scholarship, and we are convinced that there is simply no substitute for doing one's homework.

We believe in the preservation of numismatic history and abhor the recent trends of conserving perfectly fine original coins  in order to secure higher grades.

We believe in modesty and discretion over hype and marketing flash.

We believe there are many ways to enjoy this great hobby and respect every individual collector's own definition of what is right for them.

And, finally, we believe that coin collecting should be fun.

Our Staff


John Agre

John has been collecting and studying coins since the late 1960's, when he began attending local shows with his father and building a US type set.  A collection that would soon expand to Buffalo Nickels, US Commemoratives, Large Cents and Colonial and Early American Coins.

By the age of 11, John was buying and selling coins for profit, gaining a lot of experience in all series over the next half dozen years or so.

While attending college at Northwestern University and then graduate school at Cornell University, getting married, doing stints living in Japan and Singapore and traveling the globe, John spent much of his spare time extensively researching Colonial and Early American coins in an effort to create a comprehensive photographic condition census of all issues.

A project that took (and is still taking) thousands of hours and, more often than not, has revealed inaccuracies in accepted population estimates and census rankings and ultimately led to John becoming a part-time dealer specializing in Colonial and Early American coins in 2001.

By 2005, the part time business had grown sufficiently to convince John to became a full-time dealer and eventually a partner in CRO with Dave Wnuck.

For the next 7 years the two bought and sold colonial, federal, world and esoteric issues of all types, helped assemble many prominent collections, placed a wide variety of great rarities and famous coins and did some significant deals, but also were equally proud to offer choice examples of relatively affordable coins to thousands of collector customers.

In July of 2012, John purchased Dave's share of the business and became the sole owner of CRO, with an eye toward continuing the proud tradition they created.

MaryAnn Agre

While John was immersing himself in numismatics, MaryAnn was going to school at Vanderbilt University, spending a year at the University of Leeds in the UK, working for the Bank of New York, then Banker's Trust before attending graduate school at Cornell, working for a start-up in Budapest, spending time in Japan and, significantly, meeting that guy described above.

MaryAnn's next job would see her running the back office for Morgan Stanley Asia in Singapore, a role that had her overseeing US$2 billion in trades, working 15 hour days, answering calls at 3 AM, eating the occasional scorpion on shrimp toast and taking those loooong trips from Singapore to London to New York, all experiences that make her uniquely qualified to run the not-quite-as-large back office for CRO.
