This is the most recently discovered floating die clash.  It was spotted by Bob Mohan in association with a known cud that is listed in The CUD Book Supplement (Margolis and Thurman, 2001) as LC-93-2R.  A large die fragment broke away from the reverse die and its working face was struck by the obverse die.  A large, incuse letter "E" was transferred from that fragment to the field between and surrounding the letters "IN" (from IN GOD WE TRUST).  That letter E comes from either the word ONE or the word CENT.  Some erratic die damage -- also from contact with the fragment -- can be seen above the incuse letter.
