Looks like a linear die crack to me.
Artificial Chinese aging!
I would first make sure there are no key, semi-key or mint state coins. Those should be conserved individually on their own if present.
Left coin appears to have been plated.
That is a genuine error called a CUD. When the rim of the die breaks the compressed metal fills that area and causes a distortion 180° across from...
Thank you for your service to the hobby Jack!
NO! Generally you want your final step to be an organic solvent to dry the surfaces. Water is the catalyst to corrosion. With VC I like to use ACS...
Thank you from another Hungarian (by decent)! :)
You're getting old, they don't specifically "call it out". You're thinking of the old sniffer video where they had a sample of MY obsolete product...
HUGE improvements!
Indeed - I think a lot is also politics. It's the same old arguments blaming both sides of the isle for the "problems" it would create to stop...
Production needs to HALT on the cent immediately. NIFC is fine, the Mint could haul some money selling them if they became the only source. All...
It would take a much more sophisticated analysis than the "sniffer" IMO.
Good conservation, I liked the steps you took. A little VC goes a long way! With experience you'll be able to complete a conservation with just a...
We'll have to take his word for it. :)
All silver this old without any toning at all has been "cleaned". Some parallel lines in the left, obverse field...can't tell if cleaning...
Looks EF-45, the wheat grains still look sharp. However, the surfaces are questionable. That's an odd toning pattern. It may have been cleaned...
Most men give it away willingly and for free. LOL
Any metal containing copper can form verdigris. Silver and gold coins both contain a little copper.
This is a prime example of a VERDI-CARE™ conservation! [ATTACH]
