Some of the couterfeiters use computer generated design .. where a REAL coin is copied and electronically sent to a laser cutter for the dies. Then, there are no funny noses or weird numbers or letters. You just need to know what are the REAL attributes of any coin in question. Without going any further, the first thing that I look at for any 1858 or '59 variety is the vine break at 7 and at 2 (if there is one). A quick look at the D/C's on the Obverse also tells you a great denal.
