i need to get these coins to NCS as the PVC from the soft holder is quite evident...

Very nice coins!   (How can the coins be saved from damage by the

plastic containers?).

NCS can remove the PVC without damaging the coins... they're good at what they do...

When in doubt, bust 'em out !

Thank you for that information.  Heron went to the web site and found it to be very interesting.  However, no mention of how a 'carbon spot' can be removed.   Is there any method of treatment to remove a 'carbon spot'?

Just curious.

i don't believe so... if i remember correctly, it is caused by a non-homogeneous alloy... i might be remembering incorrectly tho...

Here's a good read, but you'll need your spectacles as the font is rather small:

Hola B-17!  Yes, that was a 'good read'...!   (I have several magnifying glass

helpers here in this 'office').    So, in all these years of hearing about 'carbon' spots it was really a 'sulfur spot'!    Learn something new almost

every day now.   Thanks for that information.
