If you wanted a degree in Metallurgy from Lehigh, there was no way around Dr. Hertzberg. You either passed his fracture mechanics class or you...
Ironically, I believe Socratic method to be the most effective form of teaching in existence. I had a professor in college (Dr. Hertzberg) who...
What you would pay is very different from what price the coin would demand in the open market. Furthermore, the OP is trying to understand how...
I respectfully disagree. Toning does not form in the appearance of white spots on a proof coin. The sneeze theory seems much more plausible to me.
The spotting on the Franklin is reflected in the PR63 grade. The Kennedy is graded PR66 which means the spotting had to appear after the coin was...
While this is an accurate distinction between FB & FSB, be aware that the TPG's only require the bands to be split (not rounded) in order to merit...
The first thing you need to be able to do when purchasing rainbow toned coins is interpret the seller's photographs for accuracy of color. This...

The steps on many early 50's "S" mint Jefferson's will look like that and the TPG's account for that when they grade them. My 54-S actually has...
Just because the machines take dimes and nickels doesn't mean people are still paying with them. I don't know who your friends are in NYC but...
I'm sorry, but I am not buying these reasons. They are excuses, plain and simple. I can't remember the last time I saw a vending machine with...
Hey Mark, What is your opinion of this coin based solely on the images?
While that is outstanding news, we need to find out exactly what happened. The curiosity is killing me. Who are our Heritage boys, Stewart, Cave...
Doug, You are confusing me a little. It seems that you have been advocating the established standards for grading which say that YES, a...
Spartan, PCGS will authenticate and encapsulate problem coins but they will not assign them a grade. The reason code is found in the first...
Kanga, I think you have nailed it. If you can consistently reproduce what you have done with this coin, you will have a very nice set of...
