I went back to the original Mac version of the fonts, prepared by Y&Y, which I purchased from Blue Sky Research in the mid-9Os, to see whether there was any mention of hinting.

There is, in the ReadMe file (dated February 21, 1995), line 307:

Most likely, the hinting was hand-made and added by Y&Y. I don't know how much of it survives in the current OpenType version.

I was, like Karl, under the impression there was no hinting in Lucida, but I was probably mixing things up with kerning: there was no kerning in Lucida, an experimental one was developed by Y&Y before they closed but it was never included in the fonts. It survives now in the form of an option in the lucida-otf LaTex package.

Attached are the two original ReadMe files that came with the fonts. The mention of hinting is in "Read Me!" (not "TeX Read Me!").
