the plate itself is mass produced, but probably stick on letters like you get at FastSign’s shops were applied to that blank plate

The fonts match. Note the open loop of the a's, or how the middle curve of the s's is thinned out in both texts, and also the overall heavy, boxy character of the letters.

The "terrorista" part is certainly not a cheap stick-on: observe the similar contours around letters that make the letters appear three-dimensional in both texts. I can't tell if the "terrorista" actually is raised from the plate surface or merely appears so. Regardless of what technology produced that plate -- whether glue or stamp was used, -- the letters are produced by the same outfit as the plate. I think, it is possible that someone at Dartmouth made many short batches of these decorative plates: some, probably, said "USA #1" (very popular decorative plate, as you know) and some said "terrorista #1".

OK. The font shape did not look the same to me.

It could have been screen printed too.

But the outlined “Terrorista” lettering would make that less likely.

Multiple screens and dry time would be an issue.

I cannot imagine a mass market for that tag.

It may be a coincidence but if you go to:

And scroll down to the Dartmouth College Link and click, you get:
