Update: I still have some more on the way, but went ahead and did some quick transmission tests. I only did a couple samples on each, and only with 1 wavelength, but edited the OP nonetheless, as results were consistent enough for these cheapies.

Spoiler alert: The piece with the coated hypotenuse did the worse. By a lot.

Option 1 (acrylic, and both were nearly identical):
.0587/.0680 = 86.3%

Option 2 (coated side):
.0496/.0680 = 72.9%

Option 3 (tiny glass set of 10):
.0598/.0680 = 87.9%

RedCowBoy: None have any claim of AR coating.

I'll re-do these and add in the remaining options when they arrive!

Dual post, but updated OP with 4th option that finally came, and a table with test results. Cheers!
