Light To Moderate Spreads

EDIT**Guess I was beat the the source by the source** :)

I don't know the specifics...but I would be willing to say "Light to Moderate" would be between No doubling and Strong Doubling. I know that probably sounds obvious but If you first get to know what the date/feature should look like with out doubling you can then distinquish Light Doubling as compared to Strong Doubling. Here are two pics of which I would say one is Light Doubling and one picture with Strong Doubling.

To me this is not a exact science. I could be way off. But this is my opinion of the two.

These are from a 2011P and are from Coppercoins website

Light-a little extra thickness than a normal 2011 and very slight notching


And would consider this Strong Doubling (alot of thickness and very nice notching)

If there is true extra thickness on the 8 and a true notch with thickness at the bottom of the 3, then it would be a doubled die. But in order to tell much of anything I would first have to SEE whether your definition of thickness and notching is the same as mine.

In other words I would have to see the coins about which you are asking.
