New subpage with coin features

How about a sub page on Numisdoc page, where coin professionals can lay down certain basic and advanced coin features:

• shapes
  
• rim types (like https://en.numista.com/catalogue/pieces879.html)
  
• shoulder types
  
• width specifics
  
• materials
  
• edge margin types
  
• safety features
  
• weight issues (like french heavy and light aluminium types)
  
• and so on and on...
  

These features should also be linked to good pictures with coins on Numista.

best regards to all...

And grading details too. I think this is a good idea.
