CTX 3030 War Nickle Numbers

They’re pretty goofy, and this has been discussed before. I have found them all alone with nothing else around at 12-08(8-9” deep) to 12-16/17 at a more normal depth of 5-6”. How they are corroded and how they are sitting can matter, along with accuracy of pinpoint, soil,etc. MOST of mine(I have a dozen or so) have been just like a normal Jefferson at 12-12/13.
