world numismatic team - kent, cory, carlos and emily

World Numismatics, LLC is located in Carefree, Arizona and owned by Kent Ponterio, Max Keech and Cory Frampton. Our office is open from 8 am to 4:30 pm Monday thru Friday. Carlos Jara manages our Latin American operations and lives in Chile. Carlos travels throughout Central and South America and attends the major shows there and in the US.

We are a leading buyer and seller of World, Ancient and Mexican and Latin American coins and currency and we stock one of the largest inventories of these items in the world. Our primary focus is on quality material and rarities dated prior to 1930. Our inventory consists of more than a thousand certified coins and thousands of notes.

We recently published “Mexican Paper Money”, a 424 page color reference book on Mexican currency which is available on our website.

We attend many of the major shows, including Mexico City, Long Beach, New York International, FUN, Chicago International, the main ANA show and others.


Max is a leading expert in Mexican War for Independence coinage and extremely knowledgeable in a variety of other areas including Latin American type coins and Mexican Republic gold coins.

Max’s expertise includes rarities from most other nations of the world.


Cory is a specialist in Mexican Paper Money and in 2010 authored, and our company published, the definitive work on the subject, Mexican Paper Money.

Cory has extensive knowledge in a variety of other areas of Mexican coinage and especially enjoys assisting customers in assembling collections of high grade Mexican type coins.


Kent Ponterio is well known throughout the numismatic community for his writing, published articles and affiliation with various renowned numismatic organizations. Over the past three decades Kent has worked for some of the largest companies in the industry, including Ponterio & Associates (1993-2008), Bowers and Merena (2008-2010) and most recently Stacks Bowers Galleries (2010-2015) where he served as senior numismatist and consignment director of world and ancient coins. Kent’s knowledge of Mexican, Latin American and World Numismatics is the perfect fit for our company. Kent is currently an officer of the U.S. Mexican Numismatics Association where he publishes regular articles and has conducted lectures at the annual conventions.

Over the years Kent has expanded his knowledge into fields of European and Asian numismatics as well as ancient Greek and Roman coins. He makes regular trips to Europe and Asia each year and will continue to do so as a member and owner of this firm. It is our goal over the next year, to expand our numismatic offerings into these fields, becoming a full service world numismatic firm.
