The Sterling Thimble and 1912 UK Half Crown came from the same site
The Half Crown was pretty much as deep as the detector would pick it up with a VDI reading,I
almost gave up thinking it was large deep rusted iron,filled the hole back in after not being able to find anything with the pinpointer the first time.....I decided to rescan and it was still picking up a feint high reading
so I dug again and after going slightly deeper than the length of the pinpointer I found it :)
Must say I was quite happy that I listened to my gut feeling and kept going.
