Rick K - First Member Posted September 26, 2020 Share Posted September 26, 2020 The grey thing mounted in this is I suspect a silver coin. Any suggestions on cleaning it to see what it is? 9 Link to comment Share on other sites More sharing options...

Joe D. Posted September 27, 2020 Share Posted September 27, 2020 Nice find Rick, was that an AQ find?? I'm thinking some sort of collectible silver coin, based on the buildup, and the setting! I don't believe a platinum coin would have a concretion like that! I would have a jeweler possibly remove the coin for proper cleaning! That way, the setting won't be damaged! The setting look's custom for what it is holding, and is very nice! Let us know when it's cleaned! Post a pic!!👍👍 4 Link to comment Share on other sites More sharing options...
Rick K - First Member Posted September 27, 2020 Author Share Posted September 27, 2020 Not AQ. Last year - either Nox 600 or CZ6 I was using both. 1 Link to comment Share on other sites More sharing options...
kac Posted September 27, 2020 Share Posted September 27, 2020 Coin or emblem maybe. Platinum would be pretty clean. My guess silver. 2 Link to comment Share on other sites More sharing options...
PPP Posted September 27, 2020 Share Posted September 27, 2020 Just use electrolysis,it takes out the build up crost on the silver and the gold becomes shiny as well Link to comment Share on other sites More sharing options...
okara gold Posted September 27, 2020 Share Posted September 27, 2020 I would use electrolysis. Just keep an eye on it, so you don't go too long. Here is a silver I cleaned a few months ago. I don't usually clean any of it, but this one stirred my imagination. Just used a small battery charger. 4 Link to comment Share on other sites More sharing options...
Compass Posted September 27, 2020 Share Posted September 27, 2020 I agree that electrolysis would probably do the job but I would proceed with caution. That could be a valuable coin being that it is set in gold. I agree with JoeD and would probably have a capable jeweler involved. 6 Link to comment Share on other sites More sharing options...
tvr Posted September 27, 2020 Share Posted September 27, 2020 For electrolysis, I use a model train transformer and watch it carefully. Less power than the battery charger shown above, adjustable and yet I still need to watch to make sure I'm not loosing the silver too. 4 Link to comment Share on other sites More sharing options...
