You can see some of the Ni on the reverse. Your dime likely spent some time in the ground. I think @paddyman98 has a good example picture of these that he found while metal detecting.
No there is none on the reverse its my camera I took a side picture look at the edge the dime to the right is a 1970 normal thickness and the one to the left is the one in question it thicker and weights the same
Environmental Damage is what caused your issue on you Clad Dime. I metal detect and have found hundreds of Dimes such as yours affected by the elements.
When you say it weighs the same? The same as what? the other dime or a penny? what is the weight? thanks
If it has the same weight as your other dime it can not be a wrong planchet error. If it was struck on a cent planchet it would weight 3.11 grams instead of the 2.268 grams your coin weighs.
copper penny would weight in excess of 3grams! The dimes weigh between 2.25g for clad and about 2.5 grams for the silvers. If your coin weighs less than 3 grams it is not a dime struck on a penny planchet. The Zinc penny Planchets weight less and are closer to the dime weight but that is post 1982 not 1969 as this dime looks to be.
I would seriously take many other close up pictures. measure the diameter and thickness of the dime. Look up other countries planchets and see if it may meet the requirements of a foreign planchet. or if you dont care about the money submit it but dont be surprised if it comes back as a damaged 1969 dime.
@Mark Morris - Some of your tips are good but I think you would be doing OP a favor by not leading her down a path that is not what her coin in question is. It is an environmentally damaged dime. OP needs to (but so far has refused to) learn.
I agree to an extent, Sometimes, but in this case her taking and doing a little problem solving may show her what it is. I opened two books and got all the information i needed. I am trying to lead her to the water... aka books...
As have we here. She's been given plenty of resources. Funny you mention leading a horse to water. I believe I used that same phrase in another of her threads. I am hopeful she will get it but I've not seen any real effort on her part even after being given lots of resources. That's the last I'm going to say on it.
@Mark Morris Talking about US coins struck on foreign planchets.. I saw this amazing Mint error recently.. and it's a Dime! Not my coin -
Watched a video on this one today... http://www.icollector.com/1974-50C-Kennedy-Half-Struck-on-a-Taiwan-5-Planchet-_i6396814
