Not sure when I hit that mark but it was sometime this week. I decided to repost this coin as it was an Experimental Anti-Tarnishing Agent used by the US Mint. It was used on the Sacajawea Dollars and it failed miserably. Not to many of these coins around. It was graded as a Mint Error but I have difficulty in saying a failed experiment is an error. I hope my post are somewhat exciting to others and that we all continue to learn from each other.
