The last digit was damaged by a coin wrapping machine.
Sorry to be a killjoy, but the second strike was administered by fake dies. The first strike is too little affected by the second strike. The...
Sounds like a case of blistered plating. It's caused by impurities or subsurface corrosion beneath the copper plating. Unless it's a truly...
It looks like a normal dime that's stained a copper color. I find these periodically in pocket change.
This nickel was dissolved in a corrosive substance. These altered coins are called "acid jobs" although it's not clear whether the fluid is an...
I agree with those who've diagnosed it as a capped die strike. In other words, it was struck through a late-stage obverse die cap. A nice find.
I wasn't aware that any work of mine was being featured in Coin World this week. Since I still haven't gotten the March 26 issue, want to tell me...
The weight will fall within the normal range of variation for dimes. The extra copper is too thin to add any appreciable weight. If you've got...
It could be "sintered plating"/"copper wash" error. Various theories have been advanced to explain the unexpected thin dusting or thin layer of...
Vandalized outside the mint.
Definitely a "squeeze job".
If 10% of your error coins have dropped letters, then you're probably dealing with something else. Dropped letters are rare, and I have not seen...
Given its state of wear, I'd estimate this off-center Indian cent would bring $125 on eBay.
I picked up two state quarter dropped letter errors some years back on eBay. In both, some of the die fill is retained. I paid about $40 for...
Yes, this is (or was) an encased cent. The pushed-in rim is characteristic.
Most likely it is a case of finning. Tapered planchet errors are very rare on clad dimes. Still, you should weigh it to the nearest 1/10 of a...
A dropped letter will be incuse (sunken). That is unless the material is retained.
Yes, it would make a good subject for an article. You can send text and digital images to our editor, Frank Leone, at flrc@aol.com. If you want...
This is either a rolled-thin planchet or a split-before-strike planchet. The striations on the reverse face could indicate the latter, but they...
I have a few coins with this peculiar duplication of letters in the form of split plating. I believe mine are all broadstrikes. I don't have a...
Separate names with a comma.
