Two of the year sets (1959 & 1962) are sealed, as from the mint, the others are as shown in the photos. Sets are free of tarnish or blemish and come with original envelopes (except the 1957 set). REVISION 6-11-24: The photos of the 1956 reverse was out of place and had a photo defect.
It was replaced with the correct one, and the 1964 reverse was in the wrong place. These are corrected, I hope. Sorry for the previous errors.
