A workmanlike post. I couldn’t find this by googling around; so here’s a list of the monsters in Moldvay Basic D&D, with their treasure types, in pipe-delimited format.

Here’s the link to an interactive Tableau viz I did with the data: LINK.

Make sure to use it with my treasure type generators here: LINK.

Can’t embed it here; so this is a picture of what it looks like:

And here is the raw text, in two tables (Z means NULL; 0 means no special treasure):
