Tarnished Silver US 25 Cents

Hi Gary, about those golden 1964 5c,I bought them quite a few years ago already graded. I knew my stuff back then so I would think I would have questioned a purchase of gold nicks. They were all sequentially graded and shy of cracking one I can see everything but the outer rim with my 60x. Everything is the EXACT same color and tint including the mirror field right down to every letter and number. Do I have 20 gold colored, covered, plated or just perfectly even toned 64's? I'm not a big NGC guy so not positive about the fattie. It has a reeded edge and won't go in a blue PCGS box at all but does fit the silver NGC boxes. Also has the 2" long hologram. Man I put all of my coins in the bank for decades and just recently retrieved them to market out. Kinda difficult when you don't know exactly what you have. I tend to go with possible paper discoloration except that they are all evenly toned(?) and no sign of bleeding out onto the slab. Am I a zillionaire or an idiot? You would think if they were gold pre-slabbed that NGC would have noted that on the label.Here's a # if you want to look it up 314489-027.I know my coppers like the back of my hand, likewise my goldies but this one has got me bedazzled. Hopefully someone might see this post and know right off. Until I know, I will not be able sell them to my regulars without being able to answer any and every question. That's my form of personal customer service and client retention. Plus I have to be able to sleep at night. I hope to be able to sell them soon as I am liquidating my entire 3 generation collection to supplement my retirement since Reaganomics practically wiped me out. I don't know how to cross post or even what other category to move it to to get a few more opinions. Any help would be cool.1 more quicky,how do you crack an Ncg or Igc slab without harming the coin. In my day cracking out was not considered kosher, so I have never done it before. I really have a boatload of IGC stuff that looks to me to be undergraded. Plus I can hardly get 9 bucks for a 64 red ms67 1cIGC where the same grade in PCGS is $17,500? Thanks a bunch

so Fuzz what's your take on 20 identical golden 5c graded one after the other? I found a very short forum discussion about this and the conscientious was toning but 20 toned slabs exactly alike? Interesting I posted some pics on page 1. THX

I ask a relatively precise to the point question to NGC and received this answer Max Spiegel said:
Mike,


Thanks for the question. While NGC holders are virtually airtight (and watertight), there can be some variance between individual slabs.
