Now... the collector's trusted source for the price of rare coins. currency. collectibles.

Numismatic professionals around the world trust CDN for the wholesale pricing of coins and currency. Collectors can benefit from our guidance as well. Our Collectors Price Guidance Value (CPG) is based directly on our published wholesale values for the same item. No longer are dealer and collector pricing disconnected.

Why do we need a CPG Value?
For decades the numismatic wholesale and dealer community would buy coins based on CDN (Greysheet, Bluesheet & Greensheet) values but retail pricing has been left to other vendors. Unfortunately, there has been a growing disconnect between the wholesale values we publish and the so-called "Retail" values offered by other parties which is causing a breakdown in the traditional buy-sell marketplace. In many cases publish retail prices are too high, and in others, they are too low. Neither situation is good for the marketplace.

How are CPG Values determined?
We use a sophisticated formula to determine the proper CPG value based on our published wholesale values. The formula will change from time to time, based on market influences, feedback and so on. The most important aspect is that, as wholesale prices change, the CPG values will change as well. No longer will the collector be left behind!

How do I get a published listing of CPG values?
We do NOT publish a comprehensive list of CPG values. We offer the individual pricing values to individual coin dealers, auction houses and other web site developers for usage within their site in exchange for link backs to the CDN site. If interested in publishing these values on your site, you may contact us at cdn@greysheet.com for more information. For instructions on how to use our CPG API click here.
