Hi Jeffrose! You have an amazing collection! I love the Large Cents! 
IMO, I think the last coin you have posted is another Petite Head Large Letter 1843 LC and not a Mature Head 1843. (I think so due to the more upright posture of the Obverse Bust on the Mature head (i.e., not as leaned forward as the Petite Head), the difference in the hair curl under the bust (less curl and extended much further to the front of the bust on the Mature Head, i.e., the Petite Head curl points to the top of the 4, and the Mature Head curl points at the 8)) and the base of the Bust itself extends to over the 1 versus stopping over the 8 on the Mature Head.
