Is This NT Or AT ??

Zach, no offense intended, but I think you should go slow with the TPGs until you get a much higher feeling for the 'details' coins, or it is a money drain.

No offense taken

I actually wrote out all my grades prior to my submission, I actually did fairly well. The "$" amount is how much I paid for each coin so most of the coins were worth getting graded based on what I spent but thats my opinion.

I screwed up on the Mercury Dime, went a bit overboard in an auction for the coin.. I'm just glad it received the "FB" designation, I had to call them to see since the email doesnt go out till tomorrow.

PCGS just received my 1914 Proof Barber Dime today, I'm a bit anxious for the results on that one but the waiting game begins once again.

 

I wish someone would explain how elctromagnetics will tone a coin . I thought that toning was a chemical reaction between the silver oxides and sulfer . Or does it just accelerate the toning like heat would ?

 

I personally feel that it is a way to pretend it isn't like other AT, as he can say no heat, no chemicals, and people can pass that on when they try to flip the coin. Knowing that the electrons in alloyed metals do have many surface related actions ( such as the 'skin effect' of electron travel) , the electrons do not become permanently fixed, as one might expect if electromagnetics produced permanent toning ( due to chemical bonding of said electrons). I think it is chemical or heat produced by induction ( or both) causing AT. I have seen some bus bars of copper alloy becoming beautiful shades of blue due to heat. If I could find a true scientific paper on it, it would be interesting for sure.

 

The "electro method" creates the colors due to heat, oxidation and differential melting of dissimilar metals within the matrix.
