Some time ago I bought a digital caliper from Aldi for measuring finds precisely. I’ve now added a set of jeweller’s pocket scales to my armoury for weighing finds precisely. All I need now is to find some precious metal to weigh.
There are plenty of these things about, virtually all made in China. I went for the On Balance Truweigh scale which weighs up to 100g in 0.01g increments. It also weighs in dwt (pennyweight), grains and carats (?) and needs a 100g calibrating weight to initially set it up and then to keep it accurate.
It struck me that pennyweight is precisely that – the official weight of an English silver hammered penny.
