Which Dime? in 1923 Dimes were struck on silver and a modern Dime is a Cupro-Nickel with copper core.. Both sound different.. Think about it
I totally disagree...if in acid this specimen would have more damage. It does show signs of being in the ground or exposed to environmental causes. You may wish to research what countries in that time peroid that the U.S. mint produced coins for other countries. As a platchet from those strikes may have been in the hopper then found its way into the chamber while striking U.S.cents. But no way is that the work of acid...as acid is unforgiving of any surfaces it on....and this coin would of been eaten up a lot worse than it is.
It has the look of a well worn coin that was pulled from the ground. Different types of soil can do funny looking stuff to copper cents.
How it sounds is meaningless. If it was struck on a dime planchet ask yourself, what would happen? A dime will fit into the coining Chamber of a cent but what is the result? This coin is a cent struck on a cent planchet. All the details are there. So why is the weight lighter than normal? Circulation, environmental damage, a thinner planchet are not a few reasons. It's normal and it's damaged.
So a few on here thinks they can look at a photo of a copper coin and can determine if it has been exposed to acid or dug from a acidic soil. There is no way , Acid is acid no matter which type it is. I have found many old copper coins from metal detecting and if they were in the ground for a long time they were a total mess with a thick dark brown corrosion on them. When the corrosion is cleaned off them are always pitted beyond hope. Just ask anyone who uses a metal detector.
Here are more pictures here is a dime and here is the pictures of the penny and not sure if it is a different metal.
It looks similar to a dime. Kids back in the 50's and 60's manipulated cents into the size of dimes and used them in soda machines.
Environmental damage/ acid has eaten away some of the metal. Since a dime is smaller than a cent, if a dime planchet was struck in the penny hub/press, your coin would be silver, and the complete penny rims would be broken and not go all the way around. Something happened to this coin (damage) in the almost 100 years after it was minted to arrive at the condition and weight it is in now. It's almost worthless.
