I was lucky enough to get out and enjoy some rare sunshine yesterday with Flysar at a 1920's park in Portland, OR. We came to the conclusion that the park was cherry picked hard... we both found nickels and zincs, a few coppers but not much else. The highlight of my day was stumbling upon my first V nickel and my oldest coin since starting hunting. As it came out of the hole, I called Flysar over to take a look... it was only 3 or 4 inches down in a wooded part of the park, just off a walking path. I was using a modified coins pattern at the time, in Fe/Coin... and I had my combined bins set to give me the same high tone for nickels and copper/silver.
The first odd thing was... the tone was high, but the ID showed zinc penny (12-36)... and I dug the target thinking it was a zinc. After the V popped out, and Flysar had a look, we ran it across the coil again, and it was a solid nickel signal (12-11 / 12-12).
It was obviously pretty corroded, but we were both easily able to make out the "190" on the year, and the "V" on the back... Flysar even made a comment about being able to maybe see some detail on the coronet. I wiped the year a little to clear the dirt and I was able to make out the "7" making it a 1907. This is the second odd thing... I tucked the coin in my shirt pocket, away from any other coins, and went about my hunt. When we finished I pulled it out to take another look, and we both could see that a lot... and I mean a lot of the detail had gone away compared to what we saw out of the ground.
I got home and did a light wash with soap and water, and a bit of baking powder paste and it became harder and harder to make out any identifying marks... It was almost as if the detail was corrosion on the raised arease of the coin and as it dried and flaked away, so did the detail of the coin. You can see in the pics that some of the raised parts of the coin now appear to be concave rather than raised (the "190" and the lettering on the back)... and the "V" is non-existent.
So, a few questions for the forum...
Have you ever experienced this type of reaction on a coin after it is out of the ground? And should I try to clean it (any suggestions on methods) or just leave it as it is? It will be a coin in my collection, so I'm not worried about lowering value (and 1907 isn't a key date).
All that said... it was a great day in the park with a good friend and I'm thrilled to have found a bucket lister!
