1999 D nickel. Weighs 4.3g. I can’t figure out what’s going on with it

I weighed it then another nickel then weighed it again

It appears to be a rolled thin planchet. I'm not sure if it is within tolerance, but its an interesting find.

 

Yea. I almost put it in the spend pile but thought I’d hold on to it and decided to weigh it today. But just can’t wrap my head around what’s going on with it

 

I'm thinking a corroded Nickel.

 

Environmental damage still 5 cents.

 

Agree with the others, environmental damage/corrosion.

 

they do slab coins that are underweight

 

how can i send a pic to you, private message does not have that option unless you are a supporter

 

For the coins you pictured, a third party spent a few cents each applying a decal or a layer of plating, and then sold them for multiple dollars each. Numismatically, they're just damaged coins.

 

they are coated with acrylic or something like it, edited i got them for 2 x face, i bought about 200.00 out of a dealer's junk box.. there was a set of state quarters plated gold, i sold it for 70.00 at the last coin show, i think it cost me35.00 108 quarters i think in 5 cases, he was giving it as a gift for Christmas, people do buy junk, i have made a living doing it all my life, one mans trash is another man's income..i ain't afraid to climb in a dumpster, (though cannot now due to health constraints, lol)

 

It's actually.. One man's trash is another man's treasure

 

I KNOW I JUST adjusted it, hey do ya want that quarter< i;ll give it to ya for free, it is weird, coated in plastic resin or something, except for the rim..doubt i can sell em, and cannot bring them to the bank cuz too fat, they would not go in counting machine

 

Yes but I don't think that's an actual mint error.
Corrosion can male it weigh less. They won't attribute a damaged coin.

 

true
could not tell from his pics what was going on..but acid might be the ticket

 

That's because the counting machine has a laser which will reject such coins. It's post mint alteration.

Dude now we are hijacking this thread by changing the subject.. Do you want the moderators to ban us?


Don't respond! Stick to private message

 

sorry for hitchin a ride on yer post, respect...

 

/ Happy Holidays all/don't ruin it guys please.

 

It’s fine really. I enjoy reading the responses. It’s only educating me on things I didn’t know. The coin doesn’t feel like corrosion. Meaning I don’t feel corrosion pits. But I’m no expert for sure. Thanks for a the comments. Keep them coming.

 

So if this coin is corroded. Then it holds no value. What could I clean the corrosion with to test the theory. Baking soda and vinegar?

 

A nickel is made from an alloy that is 75% copper and 25% nickel. In order to remove the staining and corrosion byproducts, you need to know what chemicals caused the reaction and what components in the alloy reacted. Not an easy task. It can be a lot if trial and error.

You could experiment with a variety of acids and chemical dips to see if something works. Actually, experimenting on damaged coins worth face value is a good way to learn the affects of cleaning. Just remember, what works for one coin, may not work for others. That's where a lot if experience, a little chemistry knowledge, and a little metallurgy can help
