CR9E is the correct plug, the number denotes the heat range, ie the length of the insulator nose.
The plugs are not sealed when fitted so there will be some corrosion to the nut.
Yours don't look too bad for colour, but if you don't know the history I would replace them anyway with the correct plugs.
