Been lurking for a while, decided on a Tesoro Vaquero. First Day with it decided to take the son in the backyard and what do you know a Spanish Reale in Virginia. Found about 4 inches deep near a large tree in my yard. Appears to be 180? . Think the son is hooked now.
A great find. Congratulations! Date looks like 1808, I think. If you wish to clean the coin, try dipping a Q-tip in acetone (fingernail paint remover), and wipe first one side, then reverse the Q-tip and wipe the other side. You should get a cleaner coin. Acetone will not remove silver nor pit the coin, and only reacts with organic material.
