These coins were pressed in machines located in Mexico. I’m sorry that the pictures are not clearer, I am not the photographer.
The 4 bi-metallic coins pictured in the top row are definite from the Monumento a la Revolucion, which is a landmark monument commemorating the Mexican Revolution. It is located in Republic Square in downtown Mexico.
Here are some close ups.
Thank you, Miguel, for sharing these photos! I was especially excited to see them as I have not seen any elongated coins from Mexico before.
