I don't have a recent Greysheet but can tell you that the 1904 is as common as they come in $20 Libs.
Even in a PCGS or NGC slab, I wouldn't pay a huge premium for a 1904 MS63. There was an ANACS MS63 1904 Lib that closed for $1,601 on
ebay this month.
I'm sure Greysheet is at least $2,000 but I would find a lower mintage date if spending that kind of money.
