Not corrosion, but deposits (grease and general filth) caused by storage in PVC or similar coin album/pockets. Often this is removeable and in this instance the deposits look very minor so should be easily removed with a bit of judicious cleaning/wiping.1 point

Are you talking about Britannia's leg? The pictures are pretty poor, but I can't see this as corrosion - depending upon whether it's incuse or raised (the jury's out...) then it's either a planchet flaw causing delamination, or perhaps something like grease finding its way onto the die.1 point
