Featured 3 pairs of silver cufflinks, one pair antique Ethiopian coins, please help!

Hi,
The below cufflinks were bought in a job lot.
I would like to know more about the Ethiopian coins as I do not understand the writing. What denomination, how old are they? Google returned several prices ranging for tens to thousands. It would be nice to know if they are valuable.
One pair Egyptian and one pair maybe Mayan.
Opinions on them would be very much appreciated.
Thank you.
Kind regards,
Simona

I suspect making them into jewellery sadly devalues them but still interesting and cool pieces.

 

Hi Dave,
Thank you for the information, I wonder if you could advise on the denomination, is it 1/8, 1/4, 1/2 or 1 Birr or Gersh?
I could weigh them, maybe it helps to get closer to identify the coins.
Do they not have a year on the coin like the ones in the West?
I found the below link, but can’t associate the letters.

Thank you.

 

@Any Jewelry I wonder what are your thoughts on the cufflinks.
Thank you.

 

They could all benefit from a clean, which will also make it easier to see what they are.

The first pair is so dirty I have no idea what they are.

The second pair looks based on the Aztec Calendar or Sun stone that was found in Mexico City. If so, they are Mexican souvenirs.
There are probably marks on the back that can help with a date estimate. If you clean them you should be able to see them.

Mayans didn't have cufflinks, but you probably mean the Mexican ones based on the Aztec Calendar or Sun stone.
