Who Is PCI And Are They Reputale ?

They were at one point a premier grader, as said above, their old slabs are accurately graded and somewhat sought after. Their grading got sloppy and their reputation faltered. The new owners of the company are trying to bring the company back to prominence, with mixed results.
PCGS has a population of 20 for 1987 MS70, and that is huge for a 80's 90's ASE. Most of those years have zero to single digit 70's.
So your PCI Eagle could genuinely be a MS70, but due to a lack of trust in P{CI grading standards, it will not command the $900-$1200 price tag that a PCGS 1987 MS70 Eagle would command.

I don't know much about them, but I do know they are not reliable. I consider them to be a basement slabber, but they do a better job than most of the other basement slabbers out there.

There are five [six? seven?] different companies and owners who have used the PCI name since the mid 80s. This is from memory, so take it with a grain of salt.

The early stuff - green borders - were MOSTLY ok ... at the time. Although even there, ymmv. Most people find the two [three?] versions with the gold borders to be, um... less than competently graded.

After that faded away there may have been an intermediate company, then were bought by David Lawrence Rare Coins. Renamed DGS [Dominion grading service].

DLRC shutdown DGS and sold the name PCI and thr slab moulds to somebody who was going to do the new PCI. That never flew and after a year or so the new-new PCI showed up.

You can look at the Internet WayBack machine for the history of their website for a lot of this.

They were one of the first on the TPG scene. Over the years their grading has become inconsistent and they fell from grace. Older slabbed coins may offer a relative bargain, however, I suspect many of the properly graded coins have been cracked out.

Green? Typically I've seen it as blue, as shown here: http://pcicoins.com/ [In my head I call it the bullet train version] and I have only ever seen 2012.02/n serial #s. Not sure what it means, but even at 5 digits, that's a total volume in two years of a slow week @ PCGS.

They call themselves the new PCI, referencing the 1989 version and conveniently leaving all the Intermediates out of the picture. Including the September 2010 'new PCI' which is why I call this new-new-PCI.
