Nickel struck on dime planchet?

I got this odd looking nickel in a collection I bought a while back and I suspect that it is a nickel struck on a dime planchet.

I looked online to see what confirmed examples of such look like and they look similar to mine. Since the nickel is from 1940, the dime planchet would be silver, weighing 2.5 grams. I weighed the nickel and it does indeed weigh 2.5g.

What do you guys think? Am I right? Is it a different kind of error? Is it just pmd?

Any other ways to confirm it?

Thanks!

The nickel was dipped in acid. It is considered PMD - Post Mint Damage. The weight? I guess the person who created it was lucky to have it weigh as such.

 

yup, just acid treatment

 

Here is some information -

Agree with acid. While it weighs the same, you should line it up
with a few other dimes. If it is larger then a dime, then you know it can't be
a dime planchet. Also it has no silver patina which has a distinct look.

 

I'm a little surprised that acid could etch away half the coin's mass without altering the color more (because nickel dissolves more readily than copper). But other than that, every aspect of the coin's appearance screams "etched by acid".

 

Really interesting to hear. Looking at the link that @paddyman98 posted, it says that it should have "Uniformly mushy design on both faces." In this case, the reverse looks very "mushy" but the obverse looks fairly strong.

What do you think? Still PMD or possible error?

Looks really similar to this: https://www.ebay.com/itm/Uncirculat...=true&nordt=true&rt=nc&_trksid=p2047675.l2557

(I'm mostly convinced that it's PMD, but just want to be absolutely certain)

 

Take it somewhere to verify the planchet is silver to strengthen your being certain. if the planchet is not silver it verify everyone else.

 

I've never experimented with acid ... either now or in the 1960s
but if it was, say, inadvertantly dropped into a cup of acid (unknown type), sooner or later that acid will reduce from evaporation. So technically, it could etch one side more than the other. Also, if there was another liquid in there that was lighter that material would float up and help buffer one side.

well, who really knows right ?
You'd have to contact the person that did that to the coin .. that's the problem with PMD.

But if it was a dime planchet, you can have an expert check the planchet itself.
Nickel
Metal Composition: 75% Copper - 25% Nickel
Mass / Weight: 5 grams

a 1940 Dime would be a Mercury planchet
Metal Composition: 90% Silver - 10% Copper
Mass / Weight: 2.5 grams

Should be a fairly easy confirmation right ??

That ebay auction ... a $32,000 coin that they are shipping via Economy Shipping ???

 

Not sure why that coin came up. The coin I was trying to show was a $120 nickel on dime planchet that ended. Let's try this again: https://www.ebay.com/itm/Uncirculat...m43663.l44720&nordt=true&rt=nc&orig_cvip=true

 

cannot verify that was actually a nickel on dime planchet, they provided absolutely 0 testing to verify. people say various things to sell a coin on ebay, Found in a box of cheerios ect. don't buy that junk. id just test the planchet first.

 

I suspect you could get that effect of the reverse mushy with a strong obverse by several means. If the obverse were coated with oil or wax before dropping it in acid, for example. Another method might be to place it in a shallow amount of acid that did not reach the obverse, but that would be harder to maintain the uniform etching of the edge.

It would seem to me it would be much easier to explain that obverse/reverse difference by assuming acid than by supposing it was struck that way, whether it was a dime planchet or a foreign one. A coin struck on a too-small planchet would have roughly equal pressure on both sides.

 

I see it now
Uncertified
I wouldn't buy it as there's no verification of the planchet for that amount of money.

 

Someone playing with the acid commonly used to bring back the date on buffalo nickels might well keep playing until the weight reached exactly 2.5g, especially if they intended to pass it off as a dime planchet.

 

... after they dropped it in a box of Cheerios .. which they usually leave out that aspect of it.

 

Astroturf. You can visually see it is larger than a dime.
Making it impossible to be struck on a dime planchet.
If it were struck on a dime planchet, it would be the exact size of a dime
And all of those letters that go around the rim would not be complete.
Put a dime on top of a nickel and see how much missing space there would be near the rim.

 

Acid. Period

 

Still PMD

 

Really, your not as smart as I thought. by the way I was agreeing with everyone. and it would squeeze the silver metal out to the collar.
