Ok, first post so if I screw it up, I’m a newbie on the site (not an internet newbie by any means though). I've been lurking for a couple months after following the link to here from coinflation.com.
Anyway, I'd like to request everyone post their accomeulative sorting percentages of US pennies and after a week or two (depending on how many replies I get and how quickly) I'll come up with a nationwide (or however the people in the forum are geographically located) average.
For instance to make it simple reply with the following:
Number of pennies - 2000
Number of copper - 537
Number of zinc - 1365
Number of 1982 - 73
Number of wheat pennies - 9
Number of Canadian - 9
Number of Indian Heads - 0
And if you're really methodical (or anal):
Number of unidentifiable - 1
Number missing from roll - 6
Or just use copper/zinc if that is all you know. Please use the format so I can copy past into excel and make "-" a delimiter. If you do every row in the same order and all use the same format it'll make combining all results much easier. Also, please only post total you know to date, I'm not looking for this week out of 1000 I got X%, then a week later post again. If you don't have a sum total over the past several weeks or months only post the most recent so I only get one reply per person. I'd like to make a statistic based on all sorted coins. Ideally, yes, I would allow you to continue contributing to the pot but for starters let’s try this and see what happens.
I'd like a sample size of 100,000 to 1,000,000 if there are enough people out there doing this. I've done 4400 myself but stopped counting to see if there were really 50 pennies in the roll (hence my "number of missing from roll line") and I've stopped counting percentages altogether in order to sort more quickly. The only thing I keep track of now is how many coins I have looked at and since I take out wheats and Canadians and Indian Heads separately I can do a % of wheats but I can't do a strict copper vs. zinc. Right now I'm at 4400 looked at and I’m running about 1 in 220 pennies is a wheat penny. I have read in the sorting percentages topic that my percent is pretty close to what other people are finding. I’d love to get a large enough sample to see on average how many you need to look through to find an Indian head.
I welcome comments, constructive criticism, and most of all, stats from all users.

Did not count the wheats but seems like about 32 per 10000 total sorted.
Do not count 1982's separate, the machine just sorts copper from zinc, not by date.

| I think this thread should be merged back into the sorting percentages thread, which has wandered off topic to coin grading and pricing.... |

Yeah, would be my fault for asking about pricing of coins in the sorting percentages section....I was trying to make a one stop TOTAL percentage per any user keeping track, then shut it down after a week to a month.
The sorting percentages topic is mostly stream of consciousness topic where you post the percent every time you sort $10 worth or so, which many people have done many times. I was hoping people who posted the percent from $10, 10 times had a total tally the could quickly be assembled and we'd have a comeulative percent of coppers, zincs, wheats, and indian heads all in one place. I suppose I could read every posting in the sorting percentage forum and compile it that way. Seemed much simpler to request anyone willing to send the info to post only their total to date so I have one giant sample of data to create percentages from. Thanks to Ryedale I already topped the 100,000 mark. Be nice to have a stat for like 1,000,000. From Ryedale I can guess an indian head is about 1 in 75,000 and I had a rough idea what wheats were already.
Sure, we already know coppers are about 30% on average, I was trying for more data to come up with a more accurate indian head percentage as I searched the Sorting Percentages topic and I believe only one person said they'd found one, but I couldn’t easily say "OK, that's 1 out of X total reported", plus only 1 found could be a statistical blip and a lucky find and we could say the chance is 1 in 1,000,000. Ryedale is reporting about 1 in 75,000. If that hold up and I get replies totaling 1,000,000 sorted I should expect about 13 in a sample of 1,000,000 but so far I've only seen 3 people report finding indian heads but that could be 3 out of 10,000,000 or 3 out of 200,000, I have no way of knowing..
Just an eccentric geek that likes large number of data points to come up with a more accurate %.
Now if there is anyone out there that has been keeping track of accomeulative sorting percentages since that topic started and would post that I guess that would make this topic moot.
