It is caused by a VLDS (Very Late Die State). This means that the die was nearing the end of its life and it began producing weaker features, which caused the "fatty" letters. No premium.

Just an opinion, but it looks like a worn die.
I don't think circulation would make that big of a difference -- those are some fat letters!
Note the die flow lines. It makes me think that the pressure was adjusted to keep the worn die in use. Or maybe it should have been adjusted and wasn't.

It is a VLDS coin. The devices show the outside edge of the devices the heavy die flow. The die wear makes the devices look larger because they are taller. Note how the devices are getting longer on the AMERICA. See how they are even flatting toward the rim. Just the die showing its age and nearness to retirement.

Now that I look again after Coops explanation - the AMER letters are all spreading and flattening - and in the same angular direction. I gues that means those letters on the die are actually widening and bending at an angle and becoming more shallw from the wear on the die...(?)

Okay, I see what you mean. It almost looks like it got stuck in a machine and smashed flat. The F looks that way too. I suppose if it had been stuck and worn down it would appear more evenly across the coin.
It's a good example if you want to keep one.

Would the slight MAD showing on the left side also contribute to the "fat letter" effect?

Note the edges of the die show all way around the rim area. Just a very tired die.

I do not REALLY understand how those die flow lines are created - - - polishing? heat? pressure? does the metal on the coin actually flow?  |

How is a coin formed? It is the pressing of the design onto a flat planchet with rounded edges. The amount of pressure is unbelievable. The die flow is caused by the metal moving into the dies voids. This done several hundreds of thousands of times, make the die show wear. The die flow start being seen on the LDS dies when they get to that point. It is usually small at first, then gets stronger. How do we know that? Looking at the coins from various die states we see the wear first starts on the outside edges of the devices near the rims. They start to loose their edge at first, then in the next die state we see it continue and eventually breaks down that edge.   On the VLDS some die get used way beyond retirement. The fields and the devices seem to snow drift over each other:  When the coins start showing die flow, more and more flow lines and die wear keeps showing itself on the coins struck.  So die flow is a sign of an older die, but also is die wear.  Hope this helps. |
