...speaking of blue toned copper....what about this one?

Noticed a couple of threads discussing blue toned copper and whether certain examples are AT, NT ... anyways, my question is whether or not PCGS' coin sniffer is trained to sniff ms70 and other chemicals that have been known to impart blue toning ... I have this lovely piece of non-US (sorry) copper and it has an amazing even wash of vibrant blue with blazing luster ... it's in a secure holder so obviously the sniffer passed it ... thoughts?/opinions?

Based solely off of those pics, that blue looks much more natural than some I have seen.

Anybody know if the sniffer detection settings are the same for both US and non-US coins?

Looks good and appears to have that neat silver luster that happens on copper at times. Very nice coin even though it is not US.

From what I understand the answer would be yes as it is setup to detect contaminants no matter the coin. Molecular isotope analyzer using light refraction technology?

Now that is what I consider a sexy looking coin!
Beautiful and natural.

Superb coin. Great toning booming luster.

Not all shaded of blue on copper is AT as there's nothing on this example that would alert being non natural.

I also don't believe that they change sniffer settings for origin.

Thanks folks.

I wasn't thinking that all blue on copper means AT...this one just has such a uniform, bright wash (a bit bluer in-hand) that it at least made me think about it after reading the other threads. I don't know if I've seen a similarly blued out IHCs in secure slabs...
