Message:: [QUOTE="WingedLiberty, post: 1438479, member: 26030"]here is an example of some of my experiences comparing NGC grades with PCGS grades Here is an NGC PR67 Lincoln Cent I bought last year [ATTACH]176688.vB[/ATTACH] So I sent this into PCGS with the coin still in the NGC slab for crossing ... It didnt cross at grade. So I sent it in again this time allowing an up to 2 grade drop It graded as PCGS PR65. I sent it in a 3rd time for an upgrade evaluation, thinking that PCGS might have simply be "punishing me" for buying an NGC coin.  So this time it was in a PCGS slab as PR65 and PCGS would have no memory of this formerly being in an NGC slab.   Results ... Once again PCGS PR65. So PCGS thinks this is a SOLID PR65 ... while NGC thinks this is a PR67 ... same coin ... totally different grades. Luckily the difference between PR65 and PR67 for this particular coin is minimal ... however if this was a Matte Proof Lincoln, that difference in those two grades could be tens of thousands of lost dollars.   Upshot: BE CAREFUL trusting NGC grades ... my experence is they are typically 1 grade too high when crossing to PCGS and sometimes (as with this coin) 2 grades too high ... especially with copper and gold.   For some reason I have better luck crossing NGC silver coins at grade to PCGS.
