Can anyone Identify these two coins

The first is from Portugal, 10 Reis. The second is French, I can't tell the denomination from the pictures. Both would be minimally worth a few dollars or more depending on the exact type. Can you get higher res pictures or even a scan?

What is that 1789 Louis the XVI coin worth in that condition I have one that was handed down to me from my grandmother that was handed down to her from her grandfather. I'm interested in selling mine. Are they rare?

The French coin is one Sol or one Liard (or half Sol) depending on its size.
30mm: 1 sol
21mm: 1 liard
I can not read the mint mark which should be below the coat of arms.
Value depends on the mint mark. The small ones have a little higher value than their big brothers.
