Coin surfaces

I've been trying to understand what 'crystallization' looks like on a coin.

Linked is a genuine but crystallized coin from Doug Smith's web site. Doug describes the surface as 'reticulated'. I believe coins like this are described in auction catalogs as 'heavy crystallization.'

(Doug, if you are reading this: I have several coins that are that bad too!)

Below is a diobol from my collection. I believe it is genuine. (The dealer who sold it to me did not. He would not sell it except 'for study', and put a note on my receipt saying it was probably counterfeit.)

Under the loupe there are patterns on the surface that look like little silver rows of corn on a cob. I believe those corn-row patterns what I sometimes see called 'light crystallization' in auction catalogs. Is that correct?

(I'm putting this topic in the forgery area because crystallization is an important clue to authenticity. The topic seemed to fit best here.)
