Benchmark collection PCGS crossovers in Universal Coin auction

[kchan1111]

OK I have updated the spreadsheet after UCC auction.

The 1952(P) Penny graded NGC MS65 was sold in IAG auction for $215 incl BP. It was knocked down by 1 grade by PCGS to MS64 and went for $2128 incl BP. :shock: I thought I had made a mistake and went back to check - I think they are the same coin since both had the same distinct lovely rainbow toning.

Others like the half pennies that do crossed over same grade, the prices realised was more than doubled. And the 3d as well.

Of the ex-Benchmark coins that was sold in UCC auction, total realised + 15% BP was $74.5k. Those same coins realised almost 37k including 19.25% BP in IAG. Not bad isn't it?

Gosh how I wish my florin will cross now!!! :beg:

Let me know if I've done something dodgy.

The '52P was a 64+
So it's only 1/2 point difference.

Oooops sorry about that. I have updated it to reflect the few that were +.

A couple of the half pennies actually went up half a grade then!

Nice work. There were quite a few that didn't sell at the UCC auction going by the blank fields in the prices realised columns. All things considered not a bad earn.

I would like to say great job on your analysis of the benchmark collection.  I think it falls more or less in line with generally thinking that PCGS and NGC are close graders.  However, some coins "generally" go down a grade / half grade when crossing over from NGC to PCGS.    

My question to everyone ... does the population report play any factor in how they position the coins for grading or is it "a pure" grade?  And surely earlier graded coins might not be up to the standard of newer graded coins based purely on knowledge.  So many factors!  Learning never ends.  But I guess that is why we purchase the coin not the "label" (envy).  However, I am assuming some people love label envy because of the set registry and the price they seem to pull!

[wwwww]

It's a pure, technical grade. They claim to implement market grading but they don't seem to do this for world coins.

Grading can be done independently of the coin type so the learning factor is minimal as they're already expert graders. The key to learning to grade regardless of coin type is to analyse the surface quality, by considering this factor your grades become independent of strike detail and thus far more accurate.

PCGS should do something like this in Australia

Thanks for that. I have notice them before from your website. :good:

I also have this book from eBay...

I think what's lacking for me is seeing practical examples. A class where you get to handle coins and have differences pointed out to you between examples would be useful.

Get some of your coins in different grades slabbed by PCGS and you will have "On Hand" examples :good:

[kchan1111]

I have a set of florins from MS60 to MS66. But still good to go through a show-and-tell of each one.

then why did you ask this?

Ok so even though I have a set - and you can tell the difference between each grade. There are lots of times when I compare a coin side by side against them and get it wrong. There's something I am not paying attention to. If someone can go through examples, and explain why - that would be helpful for me.

In other words, the grading set provides me with examples of an expert grader's grade. I am interested in understanding the thought process that led to that grade.

Other things like pointing signs between wear and weak strike like lustre would be helpful.

Am I approaching this too scientifically?

For instance... http://www.australian-coins.net/showthread.php?tid=1976&page=77&highlight=Noble - comparing it with examples from my grading set I couldn't tell it was a MS63.

Come to my table at the Petersham show kchan. I can show you a few coins of the same design in different grades and can point out why they're in different grades.

Thanks Eric. I will be there. Look forward to having a chat with you.
