I was doing research on the US Proof Coin Sets. I was surprised to see that the 2002 Silver Proof Set, with a smaller mintage, is valued at less than half of the 2001 Silver Proof Set. Is this somehow due to the 9-11 tragedy of 2001? Usually, a lower mintage equals a higher value.
For some reason the 2001 Sac dollar has achieved key coin status and it's value is driving the price of both the 01 proof and silver proof sets. actually, it looks like there were 3000 fewer 01 silver proof sets than 02's. Where did your numbers come from? I am using the 06 Red Book.
My statistics on proof production was taken off the BestCoin website as I'm unable to find the Red Book mintage on the internet. I was mistaken by thinking that the price rise in the 2001 sets was due to 9-11. You say the Sac Dollar is the reason.
