There has been talk on other forums about which is bringing more of a premium on
ebay. In most coins, it looked like NGC and PCGS were pretty comparable.
I discovered today that this is not the case with all coins. For
Franklin Halves, PCGS is still the leader in the market - bringing a significant premium over NGC.
I found this very surprising since this difference does not seem to apply for the other coins that I've looked at.
