Terminal M - 1395660 - Squeaky clean, looks NIB
Model F - 1801449 - Little bit of grime on caps, mostly clean
Model M - 1397661 - also very clean, have RGB mods for it
Model M rubberdome
Prices on all these could be all over the place.
Terminal boards are OK if you already have a converter, otherwise they are hard to move, and not desirable as donors because they tend to be missing the more valuable key caps.
If you have the originals, you might be able to sell the RGB set for $10-12 shipped, and it would probably not raise the value of the keyboard itself by that much.
A year ago I felt lucky to sell 2 very clean tested F XTs at around $35 each, but prices seem to have moved up.
In recent years I have sold 2 of the rubber dome Model Ms for about $15 + shipping and you may not do much better than that. Too bad the caps won't interchange - that would practically double the value of the board.
