more sterling silver cameo questions

hi:) so do you think these could be dated back to the 16th - 18th century? there are some markings on the back but i cant tell what they are due to the way it seems to be worn in spots. could you please tell me what else to look for, and if they are antique, how do i care for them? thank you...
