I received this set a couple years ago and am looking for more info as I pretty much have no clue lol. From what I can gather, this is simply 5 separate coins that someone had "made into a set", not an actual "set". It does have the NGC cert tag on it and it does come up with NGC. According to the NGC sticker, they are "BRILLIANT PROOF". There is a 1961 Franklin, a 1964 Kennedy, a 1969 S Kennedy, 2000 S Kennedy, and a 1976 S Kennedy Bicentennial.
So, since these had previously been sent in and graded and slabbed would it be best to leave them as is or separate them? Since these were just made into a set what would be the approximate value as a set? Value individually? I realize nothing I have is probably going to make me rich, I am not that lucky lol. Just trying to understand some of this. Also, how is proof coin value determined? Is it solely the collectibility of the coin?
