Why does the 2001 proof set cost so much? I was looking on ebay and it's even more than the 1999 proof set. Is it a key date or something?
According to the Red Book and if you are comparing the whole sets, not just the 5 State Quarters, they are listed as... 1999 - S Clad Proof Set (2,543,401) $80.00 1999 - S Silver Proof Set (804,565) $300.00 2001 - S Clad Proof Set (2,294,043) $150.00 2001 - S Silver Proof Set (889,697) $155.00
