I've seen posts attesting to the same, but my own experiences have completely confirmed it

I put some of my Morgans out on eBay recently. Some graded by PCGS, some by NGC. I have two coins, with a similar book value and that have been on eBay for several days now.

The NGC coin has been visited 15 times and has a current bid of 99 cents.

The PCGS coin has been visited 1066 times and has a current bid of $192.50, which it got to within two hours of being put out to bid.

Unfortunately for the bidder on that PCGS coin, I've decided that I don't want to sell any of my Morgans right now after all, and am going to be pulling them, but the results here really surprised me. I had two other PCGS coins in this lot, and people are swarming all over them, while the NGC coins get no attention at all. The grades on all coins involved appear to my eye (with the aid of my loupe) to be fair and reasonable, so bidders out on eBay must be buying the holder and not the coin. If this trend continues, then I may have to start using PCGS for grading.

I wonder if there's anything that can be done to allay that perception? My graded coins are almost exclusively done by NGC, and I'd hate to think that I can't get fair prices for them.

PS: For those who might be interested (remember, I'm pulling them, so this is not an ad... )

PCGS: 1883-CC MS-64

NGC: 1891-S MS-64

The 1891-S is actually in better condition, I think.
