Low-grade examples of the 1855 double eagle are fairly common. The issue becomes increasingly rare in high-grade condition. There were examples of the date found on the S.S. Central America and S.S. Republic. Most of these were Extremely Fine or About Uncirculated, but a few were on the low end of the Mint State scale. The 1855 double eagle is a true condition rarity. Nearly all of the known examples of this date are low grade.
