So, stop any other organic deterioration. I don't think that changes the look of the surfaces though, they will still have the look of a less than exceptional surface.
In my case, I would put them in my bag of "Junk Silver" neither of them are worth more that current price of silver. Semper fi
I lrt them go for spot or whatever you can get. 64 high mintages, they aren't quality strikes, plenty of file and polish lines. There's nothing that points to them being worth more. Imho
You have a good point there. If the coins were closer to a gem condition, I could see doing a restoration on the surfaces.
The dime is in MS condition? Okay, if you say so. An acetone bath or soaking in distilled water isn't going to hurt them, so try it and see what your result is.
These came out of a mint set, yes after market. But none of the coins show any trace of circulation. Might try the acetone but the only thing that is likely to remove the unsightly tones is either a dip or a commercial detergent like MS70.
Anything but Gem quality (certified MS-65+ and higher) 1964 dated silver coins are pretty much "junk silver." The mintages were very high, and collector interest is limited.
Ok, John when dose a collector stop trying to make a coin look better? Is conservation a bigger topic than it should be?
I discontinued using MS70. It seemed to work great at first. Then many of the coins developed a tan tone several months after use. Some coins developed a tarnish almost immediately on contact with it. All where pre '64 silver. My methods that worked ok at first didn't change. I thought I had a bad bottle. A freshly opened bottle produced the same results. Instant tarnish upon contact.
Quite right, but I'll always go the route of acetone first. Beyond that, I'll leave it up to the professionals........especially with something valuable.
