The most valuable Professor's Letter on this list is Professor's Letter from Alternate Art Promos at $19.26, and the 8 priced copies across 6 sets are worth $33 together. Most of that sits in a handful of printings: the older the set and the scarcer the print run, the wider the gap to the rest.
If you are trying to identify which Professor's Letter you have, the set name is printed on the card and the collector number sits in the bottom corner.
