:rolleyes:
Have you had a look around first
This topic has been covered before & more than once ;)
Can't see your pics either
And it might help to find the " introduction " section ;)
 
yeah i was reading, do not clean, fine, risked, damaged, no biggie, fesh coins, can replace those,

acetone 24hrs didnt touch it

seen recommendation leave it, but milky discoloration makes it worthless im guessing, what about the yellowish ? i know probably i could find answer here, after 45mins i chose to ask :P

thank you
 
I do have a process call Electrolysis Method ( no chemical needed )
No hard abrasion needed, will take most stuff off.
( will not take milk spot as it already chewed on the surface of the metal )
 
Unfortunately, it appears that your premium "coins" have become generic "rounds", as they can no longer be sold as brilliant uncirculated.

Though there is probably no way to restore their original finish, they will always retain their value as bullion so you can feel free to experiment with different methods of restoration, without fear of ruining the coins.

Since there are likely many of us who have experienced similar toning and tarnishing effects on premium coins, we can look forward to learning about any methods you discover for effectively dealing with the issue, and therefor turn a minor loss into a potential gain for the silver stacking community.

Best of Luck !!
 
I don't think there is any dealing with it, since when atoms on the surface have been moved, and not any chemical process that brings them back exactly to where they were, at best just somewhere in the vincinity. Or in other words: bye bye "finish".

talking about milk spots, did Perth Mint find a cause for the milk spot plague that popped up not so long ago? And a solution?

That's a good one! Definitely top-of-the-heap material for the Joke Of The Day Contest!
 
PVC will be removed by acetone. You need to be patient and soak coins in plenty of acetone and leave them for days or even weeks if required. Keep topping the acetone up. It will remove the PVC but not undo the surface damage. After the acetone soak in distilled water for 24-48 hours.

Milk spots ask Bron !! Chemical polishing used and silver chloride precipitate. No easy fix for milk spots
 
I've tried boiling water / soda and it worked but it was way more work than silver dip and sometimes a cleaned (or even originally better condition) coin became again "sulphured" when not fast enough handling.
When my silver dip has been used I'll try your way. It's quite calm on my silver buying since over a year so could be a while.
