I think your string is a new format, not supported by hashcash.el. Is your format supported by SpamAssassin? Do you know of a reference to the new format? Maybe we can fix hashcash.el to support it as well. I'm CC:ing Paul Foley in case he knows more of the new format. Btw, Paul, have you assigned the copyright of hashcash.el to the FSF? Are you willing to do so? I think it would be useful to move hashcash.el from contrib/ to lisp/, but we can't do that unless papers are signed.
