Ron Guth: 1834 Dimes are found with either a Small 4 or a Large 4 in the date (the image above shows the clear difference between the two). According to the PCGS Population Report, the two types appear to be of equal rarity, though there are fewer Mint State examples of the Large 4. Of the Mint State 1834 Large Date Dimes, the most common grade is MS-64 and the highest grade is MS-67 (where three appear at that level as of May 2011).
