Stamps, covers and postcards condition and grading

Stamps:
- Mint: The stamp is in the same condition as when it was printed.
- Mint Hinged: It is as Mint but it has or had a hinge on the back.
- Regummed: Gum was added to a stamp wich had lost gum to make it looks like mint (it is not an official process).
-Unused: The stamp don't have cancellation/postmark on it but don't have gum anymore. 
- Used: The stamp have a cancellation/postmark on it. 
- CTO (canceled-to-order): The stamp has a cancellation/postmark but the stamp has still gum. CTO stamps were made especially for stamps dealer/collector. 

I am grading the stamps from poor to very fine condition (poor; good; very good; fine & very fine). When I grade the stamps, I take into account the overall condition (appearance and centering). 

- Mixed Condition: I will use that term when there are multitude of stamps that have different condition in a same listing. 
- Poor: A multitude of large faults (large creases, large tears or thins, multiple tone spots...).
- Good: Multitude of small/medium faults.
- Very Good:  Multitude of small faults or 1 medium fault and/or the perfs cut or touch the stamp design.
- Fine condition: Very few small faults or no fault at all. The stamp is well centered
- Very fine condition: No faults and the stamp is very well centered.
There are other centering terms but I try to keep it as simple as possible. 

Covers and postcards:
I am grading the covers and the postcards from poor to mint (poor; good; very good & mint). I take into account the overall condition (appearance and centering).
- Poor: A multitude of large faults (large creases, large tears or thins, multiple tone spots, rounded corners, edge damage...).
- Good: Multitude of small/medium faults due to storage problem or postal damage.
- Very Good: Very few small faults.
- Mint: No fault at all

 
I am showing the front and the back of all the stamps, covers and postcards, whatever the price. It takes me times but I want you to have a good appreciation of what you buy and avoid surprise when you receive your stamp(s).

You might also see some red marks on some photos. It is to show you where are the fault(s). I am adding these lines when I think it is not obvious for you to see it in the first sight. 

Although I check that the colours of the stamps on the picture are identical to the stamps in real, monitors screen and smartphones setting can slightly change the way you see the stamps in your device.

I am looking for way to improve my process to make you feel you that you see the stamp in real. 

I do my best to be as accurate as possible but if you think I have made a mistake, you have a doubt on a stamp or you have another question, feel free to contact me.
