Hi Dean.

When ever you ask that kind of question, you must state what the DIAMETER and THICKNESS as well as the METALS of the coin, to which you are referring.

Those THREE parameters are essential for a meaningful reply.

Beware, modern coins are often alloyed, so you cannot easily define or analyse them in simple terms.

Their ID will be highly frequency dependent.

You mentioned a 'copper' coin. Is it truly copper? Because no such coin should be 'equivalent' to foil.
(Unless the copper coin is very thin (less than a mm, or very small,less than 10 mm)

I personally don't have the T2 yet,so cannot answerer your query in absolute terms.

p.s. Passed you e-mail onto Stu.......All the best...MattR.UK.

Dean, contingent upon the amount of copper in the coin most would show up in the upper 70's or low 80's on your VDI. I have had a few that shot up in the mid 80's, but believe that was contributive to the type of soil I was detecting in as well as it having been a real wet day. Don't see how the disc, sens and tone setting would not vary the reading.

I am finding it picks up Canadian clad in the 3 or 4 tone mode best. Seems to have trouble on the 2 tone setting. Just my latest observation ,but still testing.
