I found these Palestine mandate 1 mil coins sold on a local coin market, I didn't see them in person, and they seem to be UNC.
But as far as I know, they're made of copper (Bronze), Isn't it impossible for copper to stay intact and not oxidize or even get a little rusty or pale for around 80 years?
How can copper be bronze as indicated in “made of copper (bronze)” I think you got them mixed up, copper is a metal on it’s own bronze is an alloy of copper (copper and zinc)
I am more experienced in the field of ancient and chinese coins, south-east asian coins included too!
As for the other part of my answer, yes it can stay in really good shape even after so many years
like this:
this coin is made of bronze
and as for the possibility of it being faked, slim to none, it’s quite a common coin, I don’t see anybody wanting to put in the effort to fake a not very valuable coin

I'm not sure if it is considered copper or bronze as it has about 95% copper, and I saw some examples with green rust, but it's still called bronze, I'm confused about this part

I wouldn't expect to find fakes especially from these dates, but all mint state examples I saw where orange, these seem a little more yellowish, it's supposed to be bronze (95.5% copper, 3% tin and 1.5% zinc), maybe someone would fake it as a rare mint state example…

I see… the green rust is what we refer to as “bronze disease” the green rust is just corrosion nothing that affects what the coin‘s composition is

Mint states might not usually command a high price if it’s a pretty common coin, as for the colour, any metal can change colour due to environmental factors etc…. And it might be the lighting in which they use to take pictures of the coin, these are some possible factors..🙂

Most of the examples on the coin page (and my 1927 example) are considerably darker so these possibly could have been cleaned but if someone were going to fake one these are not the years worth faking. So, possibly cleaned but authentic.
By the way, US copper pennies are really bronze like these so interchanging copper for bronze when talking about coins is common if not accurate.

I'm relatively new to coin collecting, but I see no apparent scratches or anything indicating they were harshly cleaned, and I don't think people here would professionally clean them to sell them literally on Facebook, but how would this peron manage to get 3 of them nearly in mint state!
There is no question in my mind that at least 2 of these coins were cleaned, not harshly but cleaned nonetheless. I see micro abrasions and other signs such as polishing and a “washed out” appearance indictive of someone trying to improve their appearance for whatever reasons. Not the end of the world for these relatively affordable coins. They are still nicely preserved and lightly circulated however not uncirculated as there are obvious signs of circulation. Sharper details rounded out and very fine details worn completely such as on the leaves. I would estimate yours to be Extra Fine/cleaned to Almost Uncirculated/cleaned. No, the 1939 is a very nice example but it is not a proof type coin. You will have a hard time even finding a photo of a 1939 proof example let alone be lucky enough to pick one up in a lot.

Your 1942 for comparison to 2 others.
Yours 1939 NGC 1942 Numista
I noticed the leaves missing some details too, that's what made me think they're cleaned.
I did actually have a hard time finding a 1939 proof picture, and still found nothing, so I tried comparing it to a 1927 proof and realised I'm not experienced enough to even know the difference between the normal and proof 1927 examples lol.

No, bronze is an alloy from copper and tin, not zinc. Copper and zinc alloy makes brass.

The addition of tin makes it bronze; it is possible to add different more metals in the compound, but if there is no tin it is NO bronze.
