Found at an Industrial Plant in Arkansas today. No one knows how long, but it sat in a tank of phosphoric acid until today, here is the reverse: I compared it to the thickness of a regular dime: And, as you can see in the last pic, you can just barely make out the date...2008-D. I don't think the dime was in the acid since 2008, the acid would have completely consumed the rest of the dime before now. Earlier today we were funnin' around with new names for clad and unplated coins...I find it very coincidental that a friend of mine would find a related coin on the same day. This one is definitely un-cladilated...Spark
It might also be "valuable" to show newbies on CT when they find a similar acid-eaten coin and think they've struck it rich. Steve
Wafer-thin...you can still see the reeding on the edge, too. I’ve put it into a flip, going to show it to my granddaughter Emily, who has just discovered coins...Spark
That's the main identification point about acid, as it removes from all surfaces, so the features become very 'mushy' but are usually easy to identify. The pitting also is usually relatively minor. Jim
Yes but the value of the metals in a nickel is different than the value of the metals in a dime. Get it?
First tap then distilled water. It was so thin they had trouble picking it up with protective gloves...Spark
How ya gonna make some time When all you got is one thin dime And one thin dime won't even shine your shoes.
