I just cracked open a 1969 Proof set and found the 1 cent coin had weird toning on the rim and a spot on the obverse, other wise the coin is fine.
All the other coins are pretty much perfect and from my experience with these sets will get a PR69 grade from PCGS .
The one cent coin would struggle to get a PR66 with this sort of damage.
Looking at the coin side on it looks like a dark stripe in the middle of the rim, Has anyone else come across this?
Here are some usb pic's of the rim and a couple of scans of the coin.

Packaging can't be the problem as all other coins are'nt affected,or you would'nt think so.
It looks raised like something has adhered to it,it that correct Trout ?

Looks like a candidate for a split planchet to me. The spot is unrelated I think.

I am not sure what it is but it only goes around about 1/2 of the coin.
It could be that the blank was inferior or was contaminated prior to striking.
I have opened many proof sets with copper coins in them and this is the first time I have come across this.
I can't be the packaging because I imagine all the other coins would have been affected and the whole rim not just the Centre of it would be affected.
I think the 1c can stay home while the others go on holidays.
