I noticed this half dollar was a bit off and was thinking that perhaps it was struck on a foreign planchet or maybe even struck on a different coin stock. The weight just threw me off and my brain just can’t figure it out today! So any thoughts sent my way will be greatly appreciated! Possible error coin or just old and beaten and withered?! Thank you to all you geniuses in advance!
How about "Very old, beaten and withered" like how I feel some days. Seriously. Slightly under weight. Should be between 10.886 and 11.794. It is worn though also.
What happens to a coin that has been in acidic soil, is the copper deteriorates faster than the clad layering, if the coin gets eaten to much (looses weight) the third side looks like a couple rail road tracks. Your coin is a good example of a environmental damage.
So it totally sounds like you’re saying I can sell this for $1,000,000! Oh wait, AND you want to buy it! Woot woot!!
Seeing this, denotes that the softer core of the coin has been attacked and eaten away by some acidic material. Whether it be acidic soil, or laying in a cup holder that had some Coke or other soda, spilled on it.
To be struck on a foreign planchet the coin has to be smaller. (Foreign coins are not the same size/weight/metal content as US coins, except Panama and Bahamas (1-1 with the USD) and some of those are not the same anymore as well.) A larger coin would not fit, so it has to be smaller. It appears to be the correct size. It could have been struck on stock that was a little thinner than normal. The regular weight is 11.34g at 10.61 it's .73 of a gram light and is a little lighter than the +.454 tolerance. Not enough to be significant. That being said, the previous posters are correct. Acid has eaten away at some of the coin and reduced the weight.
