@jextxadore The only known copies are in the hands of collectors. They were printed with his 'Illuminated Printing' method by his own hand with his own artwork.
The rarest thing I have is the magazine that first published Edgar Allen Poe's, "The Raven", as a short story. That, a pewter-gilded copy of Keats' 'Eve of St Agnes and a gold gilded anthology of George Elliot's works published after her death that is still stiff and like new 130 years after the fact.
