Help IDing 3 old coins

[Fiwi]

These 3 coins have been found on our property over a few years. I would appreciate it if anyone can help me ID them. Thank you in advance for your help.

This one in thin, about the size of a quarter, 1766:

This one is tiny. Slightly bigger than a shirt button.

This one is slightly larger than a quarter, but is much heavier. I'd like to clean this so I can see it better, but I was afraid to since I don't know what metal it is made of, 1738

Second coin may be a Umayyad Caliphate 'fals'.
Compare to the reverse side of this coin:

Rotate 180 degrees on either coins reverse image to see the similarity.
While the obverses don't match, I believe the reserves do.

Coin # 3 - 1738 King George II Farthing

Actually it's a Halfpenny, and probably a cast counterfeit.

I agree! What makes you think it's counterfeit?

That could be it! I see the similarity. How strange it is to find 3 different coins from 3 different countries on the same property.

Just the general appearance and looks a little small in the diameter. Could be light weight also. A lot of times they won't be perfectly round, like this one.

Re: Coin #2:
Here's another comparison. Do a "180" on this left image and compare to your coin:

Similar coins were minted between circa 698 and 750 AD.
