OK here's my first contest. Below are the images of 10 half pennies. They are all graded by PCGS. Contest is simple. Guess the grades and colour codes. Contest will be scored as follows:
1pt - guess the correct grade for a coin
1pt - guess the colour code for a coin
1pt - get the grade and colour code right and get a bonus point
Example: If the coin is a MS64BN and you guess it's a MS64RB you'll get 1 point. If you guess it's a MS65BN you'll get one point. If you guess it's a MS63RB you get no points. If you guess it's a MS64BN you get 3 points.
The poster with the most points wins. If there's a tie I'll post up a penny image for the tied winners to grade to break the tie.
Conditions: You get one entry and one entry only. And when it's posted you cannot change it (I'll lock posts in this thread).
Entries Close: Friday 17 May at 8:00PM Eastern Time. I'll use the post time on the forum to determine which entries make the deadline.
Prize: A 1998 American Silver Eagle containing one ounce of silver.
Here's the prize:

Remember your first entry is your only entry. I'll be using those grades to see how you went the in the competition and not the new ones.
I can't contribute because I have inside knowledge.
I am going to contribute and I have absolutely No Knowledge. :blush:
I did contribute and I have very little knowledge. :angel:
And i even less
NOOOOOOOO..oh well, ya get that on the big jobs :) Do I get a point for trying :winkextra:

I am not even game enough to try as I don't understand the grades etc that already have been given.

Neither do I Goldie :blush: , But this is a great opportunity for me to get a grip on grading copper coins "Sheldon Style" :ok:
Here's a question for Markn & PPH, has anyone got them all right yet ?

Dunno. I don't want to lead anyone as to what the grades might be. I'll start plugging everyone's guesses into a spreadsheet later next week.
Yeah, i knew you were gonna say that but thought i'd ask anyway. :winkextra:
Robster's very uninformed guesses.

My first attempt at grading using PCGS. It's a fantastic way to get people focused on PCGS system. There are a lot of grading classifications though....given their success, their system clearly has some merit.
And just to re-iterate, that's a great set of halfpennies.
Only 4.5 hours to go people. I've started plugging the grades into the scoring spreadsheet. Someone has guess 5 out of 10 right!
Can i change mine?
I don't think so.
QuoteConditions: You get one entry and one entry only. And when it's posted you cannot change it (I'll lock posts in this thread).
It's quite exciting. I can't wait to see what the actual grades are. Given this is my first foray into PCGS, this type of contest goes a long way to getting to becoming familiar with pcgs.
In short, NO Matty, tried that and failed :)
Quote from: 'enworb' pid='15101' dateline='1368769298'Can i change mine?
No for two reasons. 1 it's against the rules. And 2, you've seen all the coins in their slabs and that would be cheating.

Just a suggestion Mark, But why not just put up the grades and let us check them on our guesses.
A bit like checking our lotto tickets :ok:
OK results are in.
Here's everyone's guesses. The green guesses are correct ones. As you can see Coin 2 is was guessed correctly the most with 11/14 entrants (79%) getting it right. The hardest coin to get right was coin 4, with just 1 out of 14 people (7%) getting it. Nevol and Echidna managed to get 5 out of 10 coins correct.
(http://www.australian-coins.net/images/grading-comp-1.jpg)
Here's how you all did with the numerical grades. You got the numerical grade right 11 out of 14 times on coin 1,2 and 9. Toughest coin was coin 6 with just 2 out of 11 guessing it was an MS66. Enworb did the best here with 7 numerical grades correct. The lot of you managed 63 out of a possible 140 points, or a hit rate of 43%.
(http://www.australian-coins.net/images/grading-comp-2.jpg)
Here's how you did with the colour codes. Coin 2 was the bolter here, with 13 of you getting the RB designation correct. AJ and Echidna managed a 80% hit rate, well done to both of you! Overall you got 82 out of a possible 140 points or a hit rate of 56%. Funnily enough if you'd just guessed RB for all coins you'd have got 8 out of 10 correct.
(http://www.australian-coins.net/images/grading-comp-3.jpg)
And here's the final results. The winner on 18 points is Echidna. Runner up is Nevol. Three people tied for third. Well done to everyone, it's tough grading from images and especially so for Perth mint copper. You all did exceptionally well. Certainly a lot better than I could have managed.
(http://www.australian-coins.net/images/grading-comp-4.jpg)
Wow I can't believe I actually got 3 correct.
I am an absolute dumbo when it comes to grading coppers :Dance:
Well done Echidna, You Da Man :yahoo::wavemulticolor:
Thanks for the contest Mark it was great fun :good:
I've been learning about PCGS grading the hard way.
Congrats on the win echidna well done... I gave it my best, I'm glad I got a few points
Matt
second that motion..well done mark even if ya did rip me off..I can't remember what I wrote but I know got more than that :laugh2:
cool comp
well done guys as I reckon it was hard
I had a piece of paper somewhere here on my study table with my guesses
never got the guesses lodged!!
and of course, can't find my piece of paper to compare the answers!!
ha ha
Congratulations echidna! Well done! :yahoo:
Thanks markn, was kinda fun learning.!!!
Thanks for running this Mark.
Congratulations Echidna.
Well done Echidna!
Thanks Mark for a great training tool and making it fun.
Now off to the optometrist to see about my colour blindness.
Pedro
I really don't understand the colour coding yet obviously, i don't get the RB designation when there is absolutely no R in the coin whatsoever.
BTW well done to those whom did do OK.
