1860 G$20 Clark, Gruber & Co., K-4 VF30
Greysheet & CPG® PRICE GUIDE
The Clark Gruber “Mountain $20,” has been considered a key to the pioneer gold series since the early 20th century. Today, there are only 15 examples encapsulated at either of the third- party grading services, and a trio of genuine, ungradable examples are known. There are three uncirculated Mountain $20s in private hands, and any lustrous, original coin would qualify for the condition census. In 2006, numismatists Andy Lustig, Ron Karp, and David J. McCarthy discovered a proof striking of the Mountain $20 that apparently traced its provenance back to Emanuel Henry Gruber.

All CDN prices are based on proprietary market knowledge and technology developed by CDN Publishing, LLC.
CPG® prices represent retail levels. Collectors should refer to CPG values as a starting place for their negotiations, or auction bid reference.
Greysheet/Greensheet prices are wholesale market levels for collectible coins/paper money intended to indicate what a dealer, or wholesale, buyer would pay for the described item in the specified grade. Greysheet/Greensheet represent "sight-seen" values based on a buyer's in-hand review. The actual value can be more or less than this depending on factors including eye appeal and market timing.
Bluesheet (NGC & PCGS) prices represent the highest sight-unseen offers to buy on dealer networks like CDN Exchange. In many cases, there are no active sight-unseen buy offers, so CDN looks to the recent lowest market values for such an item. For this reason, Bluesheet values typically represent the floor of the market for the specified item. CDN only tracks Bluesheet on certain items.
CAC prices are for U.S. coins that meet the standards of the Certified Acceptance Corporation. You can learn more about CAC on their web site.
Price movement is indicated for price changes in the last 30 days.
The prices listed in our database are intended to be used as an indication only. Users are strongly encouraged to seek multiple sources of pricing before making a final determination of value.
