Proof Mercury Dime & Walking Liberty Half NGC-PCGS crossover/grading
On eBay, there are many proof mercury dimes and walking liberty halves graded by NGC as 67 or 68. These are often priced hundreds or even thousands of dollars less than the PCGS graded 67s and 68s. I am wondering if this is because PCGS is more strict regarding these issues or if it's just because NGC coins often just have a lower sale price for some reason. If one bought an NGC PF-68 Walker and tried to get a crossover to PCGS for the same grade, would it likely be successful or not? I'm just wondering because it does seem like many of the NGC graded proofs just seem to be of lesser quality than a PCGS coin at the same grade. Does anyone have experience with this, or had any crossover attempts, successful or unsuccessful? Any info is appreciated.

PCGS: virtually perfect, attractive original surfaces without much toning.
NGC: Splotchy, unattractive toning that decreases eye appeal. Not too much going on otherwise.
Yes, I am wondering this because of this discussion:
These Weinman designs are growing on me.
