1967 George Washington 5 Cent variations

well though i had this all done in my album ,came across these other beauty's other day going through my stamps , all are 11 x 10 ½ , all are tagged , 1&2 im thinking redrawn , 3&4 original but the variation between all of them is HUGH !!!
1,3,4 have post marks , 2 is new, What do you think ?   

Thanks
