china plates/dinnerware

I have full set of dinner ware that was my great grandmothers and a plate with a date of a few centuries ago.  It has all been passed down to me and I dont have any idea on any of it.  I would really like to know how much the value of these items are so I can sell them, I dont have any attatchment to them and feel they would be better off with someone who can appreciate them.  There are a few that are more recent but no clue on them.  Any info on these would be greatly appreciated. The dinner set is Dynasty Fine China.  It says 2002-20 on back of plates, also says Rapture, made in China.  The last supper plate is warranted in 22 Kt Gold.  The plate with the roses on it has a date of 1658 on the back.  My great grandmother passed it on and said her great great grandma passed it on to her.  The plate with the 3 women on it has a marking on back that says Bavaria.
