I, too was a victim of the "sealed" proof set. I got what I wanted, which were proof sets from the early '60s, but all I accomplished was paying an extra $5-$7 a set. I began to wonder how there could possibly be so many unopened proof sets from 40-50 years ago? Didn't any of these people possess any curiosity about what was inside? The folks on this site straightened me out, though. Old coins in new envelopes = higher profits.
