In 1969, Jim Ruddy stunned the numismatic world with the discovery of an 1888/7 overdate. A small portion of the 7 is visible under the left half of the final 8 of the date, inside the upper loop, and protruding from the upper left edge of the top loop. Various Die States exist; for example, Die State B has a large rim cud on the obverse above TE of UNITED. Only two Uncirculated examples are known of the overdate, both of which were discovered by Ruddy! One example, graded MS-64 Brown by NGC is illustrated below.
