40% really 80% ?

[harris1]

Ok so been Crh for a few months now ( recently out of the blue layer off from work and decided to sell what I've stacked. The guy at local shop puts my pre 70 halfs in some machine and they all come up at lest 81 percent silver ? So why does everyone call them 40 %

We call the 65 thru 70 40%'s because they are 40% silver. I suggest you sell all to this guy....when u have money in hand pm the rest of us and tell your guy to brace himself....he's about to get ALOT of 65 to 70s....sell sell sell!

Of course they're going to going to show up as 80% silver in an X Ray machine because they only analyze the surface layer. They're decent for finding out whether something is lightly plated or not without acid testing it, but as for the exact composition, they're pretty inaccurate.

The reason they're going to ring up as 80% silver because the composition is 80% silver on the outside but a 79% copper and 21% silver core.

I've seen those machines ring up sterling as close to 100% pure and as low as 80% pure. I've seen them even show that a silver dollar was 3% gold! They're pretty good as a guideline, but certainly shouldn't be relied on for exact specifications.
