Remind me to be careful who listen to on forums. One suggested using a toothpick on coins but that creates scratches. At least this coin already had issues.
Almost all ancient coins recovered from burial need to be cleaned, and acetone is virtually useless in these circumstances.
I think he is angry at coin collecting. We went to Amsterdam, though! http://images.mrbrklyn.com/israel_01_2016 I was looking at coins on ebay and most seem whizzed. I wonder if my coins were whizzed and sold on ebay.
That's just how we do things around here. There any many threads with good information/conversation that could have more input added to it.
Could be that Ruben had about 64 threads going all at the same time. I liked Ruben. He left here for his own reasons.
Nuts! The toothpick does not cause scratches. The debris that is moved over the surface by the toothpick (used in most cases by people who should not be touching their coins at all) causes the scratches. Toothpicks happen to be an important tool in conservation when used PROPERLY by a professional using a microscope and suitable chemicals. TYVM
