Given the recent higher proof set prices, I redid my analysis from last year.
Bid is the highest buy price, and ask is the lowest sell price I could find in the July 10, 2000 Coin World. I used the average of the two for the "rate of return" calculations

Noted by Clint Cummins: the above IRR (internal rate of return) is "nominal" (i.e. not adjusted for inflation). A "real" rate of return could be computed by inflating the issue price to current dollars. This would probably reduce the rates of return dramatically on the earliest sets (pre-1954), and make many of the returns negative (i.e. worse than inflation) for the middle years. It wouldn't affect real returns for the 1990s proof sets much, though, since inflation has been quite low in recent years.
