Hello all, :hail: I'm super new here and please forgive my lack of knowledge and terminology. I have a 1944 super clean shiny nickel. (P mint) The "IBUS" is completely missing on the tails side. It says along the top "E PLUR UNUM" This coin really stood out to me because it is extrememly clean and reflective. Do these missing letters raise the value? Whats the correct terminology for these missing letter? I've been googling all morning to learn more about this type of error and its value but I just can seem to narrow in on the right information. Thank you in advance for your help!
