Relax ....its my coin and my experiment, and its not being sold to any of you or anyone else. Yes - I am fully aware that its now a “cleaned coin” but its one I enjoy looking at again. We all got to learn a little along the way.

UPDATE !!  @sovereignsteve / everyone - I gave it a good dousing and wipe with silver polish, took a deep breath - and here are the results. Spots dissolved, gold intact, and a great start to Sunday morning ! Here is a before and after picture   

Honestly I feel like the guy in the Fosters ad who phones in for advice and gets a solution; that is the joy of this Forum👍😊. 

 

Whether I would do this on a proof Libertad is debatable , as you need to rub the polish on and off the coin ...but for bullion coins that I just want to keep nice - I will do it again.  

Finally - whether this was copper or silver , I don’t know. Maybe these polishes work on both. 

  

 

Nice! But I would be worried to scratch the coin. I have done the baking soda, tinfoil and hot water trick on a libertad proof 08, with great succes, later it gradet 69 at NGC

Cleaned or not- it remains a beautiful coin that would always be welcome in most peoples collection- it would be more than welcome in mine 😃
