Ron Guth: In 1864, the Philadelphia Mint produced two versions of the Two Cent piece, both relating to the size of the letters in the motto IN GOD WE TRUST. The Large Motto replaced the Small Motto and became the model for the remaining years of the Two Cent type. The Large Motto variety is the more common of the two. Cherry-pickers should keep a lookout for the following scarce and interesting varieties:
