S.S. Kresge mickey mouse dinner set

I went to auction yesterday an picked up some dinner sets in boxlot.. I have 3 sets each has a cup,bowl an plate.. made for s s Kresge Company (now known as Kmart) one set is a boy an girl with blue birds, another is animals playing rabbit,bear ect... last one is mickey mouse with 2 child like mice  has walt disney productions under mickey mouse, under all the  plate ,cup an bowl has Japan on the mickey mouse other 2 sets are blank all are in the orginal boxes with orginal price tags on them.. Can anyone give me approx value for each set ? an dates for each set? I think I have narrowed the mickey mouse set to sometime in 40-late 70's.. I would make a good guess to being late 40's to mid 50's cause of the japan stamp.. but I been serching online for hours an can't find a thing about any of these sets.... thank you to anyone who can shed more light on these sets.. Btw  I also listed this in the what is it section
