The 1849 $20 Liberty Head Gold Double Eagle is one of the rarest and most valuable US coins ever produced. Technically this is a pattern coin which was used for testing the new double eagle denomination design. The US Mint classified the $10 'Eagle' as the standard gold coin unit to be used starting in 1795 - the largest denomination used up through 1849 mainly for banking and overseas trade business. Although this all changed when gold was first discovered in California in 1848. Some experts estimate that if this coin went up for sale at private auction - it would be worth between $10 million and $20 million - making it the most valuable coin ever.
