Sophie since you live in Canada I'm going to add this as something to watch out for when you buy American proof sets from 1984-1992. These were the years of the dark pink boxes with the dark pink inserts. Several of these sets have been affected by what is best called alkaseltzer toning. Unlike the sets you have pictured this stuff is damaging. Several cents in these sets have been ruined. The other coin that tends to be affected is the half dollar which tends to get the ugly ring around them. So these years from America make sure if you are from an online auction make sure that you are looking at a picture of the exact set.
