Hello,
I'm curious about the values of these coins, there are a bunch of them sold on
ebay. There is a "First Strike" PCGS MS70PL that supposedly sold for $6999.95. Then an NGC MS70DMPL that sold for $6499.99. Then the price drops drastically. Finally a bunch of MS70PLs going for $3500 and a non-graded one for $3200.

What are your thoughts on this, is "First Strike" more valuable than DMPL? Are both of these that much more valuable than a MS70PL?
I have one that I wonder if it is worth getting graded.
