You buy a certified copper coin, your standard should be "I understand that at the time this coin was certified, the color designation was correct, I need to look at the coin color now to determine if that still is correct because NGC ain't paying me if it turned". I guess in regards to your question 3, all copper purchases should be considered a given that you are on your own. The certifying company just isn't liable for their grading.
Personally, I would never send in old holders unless they are severely damaged and you have no choice. The grade stated on the holder is worth different amounts to the average collector based on generation of holder. Old "soap bar" holders like yours are worth more than new holders. Either way it is a $70-80 coin max regardless right now, and only bad things can happen if you send it to NGC, aside from the fact it would also cost you money and you have no guarantee to receive the same grade.
