Would love to hear your comments. Sorry I don't have pics. I did a search for 1942 T2 Pcgs cac nickels and saw these. Cheap one was $247 while the top was $1699.
There's not really any way to offer an answer without more detail. Are you talking about offered sales prices, or actual sales records? Are you factoring the (near-impossible for this year) presence/absence of a Cameo designation? Was toning involved in any of the examples?
Your attachment didn't come out the way you expected, but it doesn't really need to. You're trying to understand how and why 2 different coins graded the same by the same TPG and both having CAC stickers can possibly sell for so widely different prices. Well, it happens every day. As a matter of fact it happens numerous times every day. Pick any coin you want, in any grade you want, and you'll find multiple examples of them selling for extremely different prices. But why ? There is no simple answer, in fact there can be a multitude of answers. And they can range from the buyer not having a clue so they pay way more than the coin is worth, to the buyer merely wanting the coin that badly, to a bidding war, to one being some special variety not recognized by some bidders, to exemplary toning on one and not the other, to virtually anything you can dream up. But the primary thing to realize is that there is no set price or value for any given coin in any given grade - not ever. Instead there is always a wide range of prices. And that range can vary from a few dollars to many multiples of any given number.
Suffice it to say that ebay is one of the worst places in the world to look up prices. Why ? Because the majority of people on ebay pay way more than the coins are actually worth.
Just don't forget that people can ask any selling price they wish, and that number doesn't have to have any connection whatsoever to real world value. A quick perusal of actual sales results indicates the minimum price you mentioned above is right about where they actually sell.
