The Haxby site is still very much a work in progress. As mentioned above the focus is only on the narrow 9 1859 cents, Rob Turner has covered the 9/8 and 1858 cents in his written work. At this point approx 237 narrow 9 die pair combinations have been documented. It is estimated that there are a few more obverses yet to be documented, and perhaps several dozen reverses yet to document. So you could discover something new.
As to die states, Only obverses 1-15 or so have been carefully fleshed out at this point on vickycents. Doctor Haxby has the information available for all the others but both Jim and his website helper have been swamped for the last few months so updates and additonal information is coming but not yet published. Attributing coins via vickycents is addictive once you do get used to the system. Enjoy!
