    Large coin - surface find - Any chance of ID?

    Hey all,

    This was found while searching for arrowheads today. I know itís completely messed up, but was hoping you may know of an ID based on shape, size and weight. I lightened up the photos a little to see it better, my hands arenít really that red lol.

    It weighs 4.8 grams and is REALLY thin. Itís copper. Definitely a coin. Hopefully the photo can help with size. I have it currently soaking in olive oil. Any advice on further cleaning? How long in olive oil should it sit?

    I know itís a long shot to ID it, but if anyone would know, it would be all of you.

    Thanks!

    Your "coin find" is in a condition we here call "toast"...

    No offense.

    I will be HIGHLY surprised if this is I.D.'d in its current condition.

    We are good here... but no one is that good ... anywhere. heh

    Like I said no offense.

    Lets let some coin guys recommend some tips on getting you down to the coin...
    IF it even is a coin... for at this point it is even hard to say that for sure.

    The only way I see you safely getting that thing "back" to legible condition IMO would be an electrolysis.

    Which you can do easily.

    YouTube.

    PS...

    This is not only the best way to salvage this coin... but highly recommended.

    You may have found a rare copper coin for all we know.

    Thanks for the advice! I am going to look in to electrolysis. I went back out a few hours later and again found a toasted one. Same size. Ugh frustrating but thatís all part of the game I guess.

    You can narrow the ID by seeing How the coin rings up on the machine. British coins, King George, ring lower, like a zinc cent. US copper usually rings higher, like a quarter.

    Per AARC’s recommendation, electrolysis might work.

    Good luck to you and congrats on the score.

    Here's another method for cleaning copper coins without making them worse. Put about 1/2 cup of Hydrogen Peroxide in a small glass dish. Microwave the Peroxide for about 30 seconds to get it boiling. Remove from microwave and drop the coin into the Peroxide and it will bubble and fizz until the peroxide cools off. Pick off any loose material with a wooden toothpick. Repeat as many times as needed.

    Thanks all! I tried electrolysis last night. It bubbled away, but oddly I did not even see a single bit of residue come off of the coin. Iíve seen some videos where it changes the entire color of the water and becomes cloudy. Mine didnít do that at all. I put the negative wire to the coin, and positive wire to the stainless spoon. Both bubbled away but I did not notice a change at all on the coin. I let it go for a good 10-15 minutes.

    What did you use for the electrolytic solution? I like Arm & Hammer Washing SODA and water.

    I actually tried it again. I used baking soda, but this time used only salt. I put it in a smaller jar this time and it started up and changed color immediately! I need to do it more though. How long should I keep it going for? I only tried 10 minutes.

    Check the coin's diameter and thickness in MMs. That's how they are measured worldwide, including usa. That may narrow down the id process. ╦╦«

    Do it just a few minutes at a time, so as not to overdo it. I use baking soda and salt water as the solution. You can shock it until eats all of the corrosion off, but it looks odd to me, with no patina.
