Morning RebelGreat finds! What is that thing in the tree, looks like some type of explosive triggering device.
Tamrock, thank you for your commentsThe areas you have access to detect, seem to be very productive. It leads me to believe the country of Mexico may have countless undercovered treasures just waiting to be found.
Thanks MackaydonYour 1/4 copper real will be a Estado de Chihuahua or Departamento de Chihuahua coin depending of what is shown on the obverse. If the legend is not readable, then ID can be obtained by measuring the coins diameter. If 26mm, then is will show 'Estado'; otherwise, it will be of 24 mm in diameter and state 'Departamento'--and be more valuable.
You're in the right spot, keep swinging.
