They are all in the original packaging and have not been opened. The glue on the 1975 to 1983 sets has worn out, and I used a small piece of Scotch tape to keep them closed. I will not open the other ones in the boxed packaging, but I can show you 1961, 1964, 1983, and 1975 if desired. All coins are there and have not been touched. These have sat in a fireproof safe that was just recently opened. They were part of my grandmother's coin collection.
