This Franklin was hammered

Check out the reverse on this. I hope it shows up in the pictures as well as it does in person. You can see Ben's profile clearly and the back of his head around the Liberty Bell. I bought it raw yesterday, the seller had it graded MS 63 - I think it's better than that, it has awesome luster and few contact marks.

<< <i>Hmmm.... While I don't doubt the luster, I wouldn't exactly call that hammered. Franklin's curl is completely missing and I the lettering on the Bell doesn't appear legible. The Bell Lines do appear better than average. >>
Good point. It is unusual to see the profile through the reverse though isn't it?

Now that you say it, I think you're right. The coin is probably well struck, but any weakness is due to poor dies as opposed to poor die spacing.
Are you saying that the areas that I have indicated are raised up off the surface of the fields or is the light refracting differently off the cartwheel effect?

The obverse is well struck and Lincoln's profile is as evident on the reverse as is Franklin's.
Can someone explain why (how)this happens?

why don't we see it more on modern proof coins?

I'll give it a try..........usually the reverse die is stationary and the obverse die is the hammer. To keep the planchet on top of the reverse die a collar is used. The collar does two things. one, it maintains the correct diameter of the coin when the hammer comes down and two, it holds the planchet in place.
Keep in mind that everything that's involved in the striking process is in precise, exact measurements of the planchet size and weight but they are all not perfectly the same, pounds per square inch (psi) in the force of the hammer, the diameter measurements of the dies, collars etc.
So here we go, a planchet enters the collar and down comes the hammer. In the early life of the die all details are present but as thousand of coins are struck, the dies, the details in the dies get flatten out. Remember, the same sized planchet receiving the same psi force of the obverse hammer die onto the stationary reverse die will result is a nicely struck coin. Why? Because the exact amount of metal has flowed into the exact amont of space allowed in the details of the working die. But when the ends of the working dies flatten out, losing most of it's intended design, heavy compaction takes place when there's no place for the metal to flow, driving the obverse design (what's left of it) out the backside (the reverse side). This compaction, if left unchecked, will break the dies. This result or action likely has a name for it. I do know that coins without most of it's intended design are called misnomers. And if the result is worse where they don't leave the mint, they are called currants which are recycled. Whatever they're called, as amazing as this may be but both have been certified especially the misnomers on a daily basis and sell on the market for thousands of dollars.
