The dime is a blank planchet and is worth about a dollar to a few dollars to someone that's interested in those kinds of errors. I think they're really neat. The nickel looks like it was subjected to some localized intentional damage by either acid or fire (Bunsen burner?). 2003 D Kennedy Half-dollar shows signs of what's called " Struck Through Grease" error. Zero to minimal premium. I discovered about 200 " Struck Through Grease" errors on Presidential dollar coins. Zero to minimal premium.. They were worth a significantly higher premium when combined with another error, such as Washington Smooth Edge (Missing Lettering) Presidential dollar coins. These were called "Double Mint Errors." |

Ah, thank you all for your responses. I really don't think the penny is simply how it toned out... in-hand, it's quite distinct from other cents from the time. I don't know if you've ever seen a Canadian $2 piece, but the penny looks exactly like the center piece of that. The scanner does a poor job of capturing it's luster, even around the edges where it is worn, it is still that bright brassy color. Heh, thanks for the info on the dime. Guess it will just remain an oddity in my collection. :) As for the nickel, I hadn't thought of an arc-welder... I suppose that might be capable of producing the appearance it has. But, it was just something that caught my eye so a snagged it... it only cost me $.05 so, no harm done " Struck Through Grease"? I take it the name is fairly self-explainitory as to how it comes about? Edited by Midnight Fenrir

I have a few of these cents that look obviously brass in color .(I have not seen anything to indicate that they have any premium value) The blank dime planchet is a mint error and should have no reeding as it was never struck . (small premium value of perhaps a couple of dollars) the nickel looks like it has had solder dripped on it ,,I have a quarter with the same effect . (Damage) The Kennedy half could be displaying some struck through oil characteristics ,, there would be no added value for such a struck through. Welcome to the forum ,, and thanks for sharing your coin finds with us ! Metalman |

Really? I thought nickels were made of... nickel Huh, the more you know.
But, it's definitely not solder, I have a penny that has solder on it, and this is distinctly different. But, as someone else had mentioned, it's probably just be metal from a welding rod of an arc welder...
Thanks for all the welcomes :) I'll probably be sticking around for awhile, I'm always finding something new here and there, and like learning more of what's out there.

Penny, was spray painted at some point and the spray wore off. "Dime" is a blank planchet. Nickel is either fire damaged or had foreign material stuck to it, or has been buried and corroded then subsequently unearthed by a metal detectorist. Half was Struck Through Grease. Thanks, Bill |

I would think that weighing the coin would be the best way to truly figuring out what it is.

Weight would tell us if the coin has had metal added to it ,but not what the metal is ,or how it got there .
I have dug hundreds of nickels with my metal detector ,,and have never seen one that showed any type of eruption or added metal .many were denegrated and corroded but not with huge lumps on them.
as for the cent being painted ? thats possible I suppose,But I know that the brass colored ones I have have not been painted . I'm looking at an 80-D sitting in front of me on my desk ,, I will try and get photo's of it tomorrow.

Hm, I don't know about spray-paint on the penny... You're saying that it's warn off, but the chemicals may have dyed the metal right? Obviously, since the coin is much older than I am, I haven't had it its entire life, so I can't vouch for it's integrity... but it doesn't seem to be changed chemically... Still, I'm not a metallurgical expert.
Huh, I hadn't thought of weighing it... But really, that wouldn't help in any way, except by possibly eliminating the fact that it has merely been melted by a flame. But really, I can tell you right now that is not the case.
The... deformity, sticks out just a little bit further than the Monticello estate would. I can't say for certain, I'm not an expert, but it really doesn't seem to be something stuck to the surface. It just... flows out of the surface very nicely, without any ridge you might expect from something being dripped or melted to it. If that isn't created by welding... I really can't fathom what could have caused it, or what it is. Thanks for the input Metalman.
What about something being smashed into the surface during the dyeing? (not sure if that's the right spelling for minting dye's)Something soft enough to not be pushed out, but hard enough to not take the image on the dye on it? Hm, that wouldn't work.. then the rest of the image would be gone. Is it possible part of the dye broke off and got stuck to the coin? And after almost 30 years of wear and use, it's become what you see now?
Maybe I want it to be an error a little too much, and it's bluring my perspective, but really, I can't personally think of anything that might cause this out of the mint. But then, I don't know enough about what happens inside of it to offer any sound guesses on mistakes. But, since the image is half there, it means it pretty much has to be afterwards, because something in the way would ruin the strike.

i have one of those blank coins, I have no idea what it is because I got it in a lot of mixed world coins.

Per Wikipedia: Brass is the term used for alloys of Copper & Zinc.
Your 72 cent is in reality a form of Brass. If you polish cents of that composition, you will usually get that effect. Auto polish is good for that. Try Blue Coral. Cents from that year are .950 Copper and .050 Zinc. Possible slight variations due to manufacturing tolerances in the production of metal for the Mint could possibly vary from that noted. No one spectrographs sheet metal used to varify exact proportions. Regardless, Cents of that era ARE Brass. As other elements are added such as Tin, Silicon, etc. the final product becomes known as Bronze. Note thsi why the after WW11 the cents were noted as Bronze since they were made from expended shell casings and no one really knows what that may have been for real.

Huh, that makes sense to me. Just a slight variance in the alloy could probably do it. Still got a proud place in my collection, it's pretty cool one way or another** Deleted3 **
I don't polish any of my coins... I haven't even gotten around to cleaning most of them. I'm not going to bother until I find a permanent place to put them... right now, they're kinda just bunched up in an old wooden box from a Canadian sipping Whiskey bottle. Mostly rolled, or wrapped in kleenex's and the like to keep them safe. Though I do have a few in those cardboard books, and a POG binder, which seems to be the best solution I've got atm.
