Numista's coin Frequency meaning with 'pROOF'

Hi everyone,

I have basic question to understand to read ‘frequency’ one of my coin.

I have Abdulaziz 20 kurus and when I check : both of the chart says ١٢ but one of them with ‘proof’ 

what is that mean PROOF ? it is exactly same money it seems.

Proof  - a high-quality coin for collectors made in small numbers from specially prepared dies

Proof—Coins struck for collectors by the Mint using specially polished dies and planchets.

Proof - A coin usually struck from a specially prepared coin die on a specially prepared planchet. Proofs are usually given more than one blow from the dies and are usually struck with presses operating at slower speeds and higher striking pressure. Because of this extra care, Proofs usually exhibit much sharper detail than regular, or business, strikes.

Thank you for the detailed response. 

So If I understood correctly, to understand coin what I have if it is a Proof or not, I might need to send to one of the coin grading company. I don't have this knowledge.

Unless you bought it (them) already identified as a Proof you more than likely have a non-proof business strike coin, especially if they show signs of wear.  If any are still questionable to you then you can post them on the Coin information and questions forum with pictures of both sides and ask for help to determine.

Old proofs like this (if that lines is correct) aren't like the shiny money grabs of today. They are rare and it would be highly unlikely that you stumbled over one in the wild. It would also be much more difficult to determine if it's a proof especially when impaired.
