Stampman, it's not flyspecking to determine the types of the one-cent 1851-61 issue (plating, however, is another matter...). It all depends on which design features you look for first. If there are recuts, then it is a Type IV, period (#9 or #23), regardless of anything else. The recuts show as darkened portions of the top and/or bottom frame lines, such as your stamp has.
