Default Leap Of Faith and the Herpolsheimer Cards
Posted By: Dan Bretta

What does SGC do to authenticate a previously unknown card like this. Are there tests that can be done? Ultraviolet light, et cetera? Can the ink used in the 1920's be found today? The cardboard?

I'm not questioning your expertise Leon because I truly believe you can handle these cards and tell if they are real or not, I was just wondering if there is anything scientific about autheniticating previously unknown cards.
