Brilliant story Andrew! His "Business associates" indeed.
Thanks for both those recommendations. The Leuchtturm DW1 looks like the sort I am after. Quite surprised by the jump in price when you want to measure to the 1/100g though
1/100 gram is essential to be able to tell apart otherwise similar coins, thus keeping
provenance and avoiding mix-ups. Bearing in mind that all
scales are somewhat inaccurate, a coin weighing in at 1.8 grams on a 1/10 gram
scale may in fact weigh anywhere between 1.7 and 1.9 grams which is pretty unacceptable inaccuracy. And for statistical
work, for determining standards, or for telling
plated coins - where an 8%
weight difference needs to be determined from uncertain starting points - the 1/100
scale offers valuable extra precision. Finally, when
selling coins, many buyers would consider 0.1 gram
weights as being effectively uncertain and may discount what they are willing to pay.
So it is well worth the extra $20 or so.
