2010 P Dime Error? Center Is Also Raised A Little (See Photo)

It looks like the die used to strike your coin was extremely worn, so what we call Die Deterioration Doubling ( DDD) is visible. This is not caused by the coin being struck twice, just from worn dies. This is fairly common on the newer Roosevelt dimes.

What is the first clue that die wear/die deterioration has affected your coin? Note the die flow lines on your coin on the fields of the coin. The lines radiating toward the rim around the bust area. That is caused by the metal moveing in that direction strike after strike for up to several hundred times. Just like a motor wearing out, the die also wear because they are doing the same thing over and over. Sometimes these lines are polished off the die. When this happens the fields are reduced. Then the mid depth devices are affected and get thinner/weaker. Then the process starts all over again forming the die flow lines. This is normal for the dies. They are made to do this. Not something that can happen, it will happen. The halo around the bust tells me this has happened before. Eventually the LIBERTY devices will start showing a wave towards the rim direction on the inside of the devices.


This happens because the of design. As the die wears, the lower profile devices start adding a wave around certain area of the devices, towards the rim. (next step for your coin) but these just happen with age.
