I don't know about official comic condition grades, and with so many comics it can vary from issue to issue, but overall I would say these comics have been read but are generally still in good condition. There is nothing I would consider significant wear on most of them, and they have all been stored in a plastic box with other comics for most of their life - out of sunlight in a non-smoking household. Regardless, please do check the photos to ensure you are happy with the condition - as what you see is what you will get.
