Die clash on your 1913 buffalo nickel.
A silver dime weighs 2.5 grams. A clad dime weighs around 2.28 grams. The weight of your coin falls within the normal range of variation for...
One easy way is to mount a quarter planchet (cheap and easy to obtain) on a wooden dowel and press a quarter into the blank surface. Then use the...
Some people do collect struck counterfeits, so I think I would be worth at least $5 - $10 if offered up on eBay AS a counterfeit. Sending it to...
I agree that the copper plating was removed. Unplated zinc cents are devilishly difficult to authenticate. You need to start with one that is...

The last digit was damaged by a coin wrapping machine.

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...
