The ultimate combination of provenance research and Condition Census listings.
Desiring a coin and finding it are two different stories. We know where many of the top coins are located and we can help you find that special coin.
We can represent you in buying and selling negotiations at all levels.
It's critical to know the history of the coin you are about to purchase or sell.
Famous pedigrees are frequently omitted, lost, or forgotten. Our research adds value by re-linking coins to famous (and not-so-famous) collections.
Grades on individual coins do go up (frequently) or down (rarely) and they can vary from one service to another. We provide you with the unvarnished history of the coin you are about to buy or sell.
We arm you with up-to-date, comparable sales prices so you can make data-driven decisions when buying or selling.
Our rankings show where your coin fits among the finest examples.
We offer the only Condition Census rankings available for type coins.
