I would be very careful of using evidence of spear length from using images on coins as a basis. The size of the coin would have put severe limitations on what could be depicted, especially on coins that show the Emperor in military dress but only the head and shoulders. Much better to look at artwork and monumental works from the same period to check spear sizes in my opinion.
