A couple of goodies from the end of last week, I experimented on one of my iron-infested sites which is beginning to dry up by dropping the sensitivity on the Nox 600 to far lower than I've dared to go before, down to 5, and shoving the iron bias up to maximum (F2-3). I figured that this config would reduce iron falsing to such a level that even the worst non-ferrous tone was likely to be a legitimate target. It paid off:
1884 and 1942 half pennies, a button (Patent Improved in gothic letter) and
another Diamond Jubilee medallion! All of these targets were within maybe two inches of the surface, and in the case of the medallion next to a big iron bolt. In fact the 1942 half penny gave me what I'd call an anomalously high tone, it was scratchy up around 24-26 rather than the usual 20-21 for some reason, definitely nothing else in the hole. First time I've seen that.
The medallion isn't in as good condition as my last one, but in far better than my first! It's also quite different to the last. It's lacking the massive die cracks on the portrait side and there's more raised detail so it's from earlier in the run if not a completely different die. It's also got Stokes and Son on the rim which the other doesn't appear to have. It's also slightly thicker and the hole has been punched in a different manner.
Also this carburetor nameplate which was a surface find with regular settings, bit of Googling narrows it down to early-mid '20s so it's possibly off an old Model T, there's a couple of pages of people restoring carbs with this nameplate for them:
