For some reason people think the proof set started in 1992 - Current. That is not true! To collect the entire proof set of Roosevelt Dimes you must also get the ones that started in 1950 - 1964.
These coins are rare to fin with Full Bands and Full Torches without paying a nice charge for them. 1956-64 are easier coins to find, but 1950-55 are going to cost you!
I guess you can call them:
Proof Set 1: 1950-1964
Proof Set 2: 1992- Current
