Got bored today and decided to see if I could answer a question I've seen on this board. The question was "When do coins get evenly geographically distributed?" I have a bunc h of nickels I decided to look at. I excluded anything older than 1960 and 1990 and up. So I limited my dat to 1960 - 1989. I ranked the years by quantity minted and where minted as well as the number in my count I compared ranking. Since a number of years in my count had the same count as other years, the year with the lower mintage got the lower rank. A rank of 1 means the highest number minted or highest number in my count.
I live in WV which means our coins initially come from Phil. When I compare ranking a difference of 5 or more I used to indicate the year was either under or over represented. In 1971 I begin to see the D being over represented which may indicated the Denver coins begin to be evenly distributed in the WV. About the same time the P coins quit being over represented.
My data: (Sorry, when I sorted the data D comes before P)
I know I only used the rank to analyze the data but my statistical skills are limited. I apologize for the formatting but I don't know how to paste it without the numbers all running together.

I forgot to say - if there is any validity to this then it takes about 40 years for nickels to get an even geographic distibution. No wonder so many of the "D" in the album my granddaughter and I are working on don't look so good.

I'd be interested in seeing something like that which represents % or # of aUNCs or better.
I'm working on 6 '62-'95Ds UNC/BU for the g-kids, missing a couple (I mean 2) each.

And if that's not bad enough, 6 also of the Littleton '97 forward. Missing '02,'04,'07,'11. Ps (decent ones) are scarce here.

Use the octothorpe (#) for columns: Works only if you are using Reply to Topic. It is actually a button:  Pressing it inserts the [cod e][/co de] tags, which can be typed manually (especially necessary when using Quick Reply). Anything between the code tags will be rendered in a monospaced/fixed font and duplicated spaces are left intact. |

Biggfredd - thanks for showing me the #. Unfortunately somehow the numbers in the columns got disorganized. Beginning with 1981 D it should be 1 30 364.8 29 and so forth through 1989P which is 63 1 898.8 3

Should be fixt now. |

Interesting data. I don't understand the quantity rank. Look at these 3:
Year Quan Rank
1965 P 1 56
1968 S 1 4
1969 S 1 55
They all have a quantity of 1, but the ranks are very different. Shouldn't they all have the same quantity rank? It might be better for you to sort the data per rank and then list the data for each one. I think the 1968 S quantity rank should be near the other two. Maybe a digit got left off? Edited by wquinn

Wquinn good catch, thanks - the quantity rank for the 1968 S should be 54. My assumption with the quantity rank is driven by the number of coins for that denomination I found with the largest number found given a rank of 1. If 2 or more denominations had the same quantity I gave the denomination with the lowest amount minted the lower rank. For example the 1968 S had fewer coins minted tah the 1969 S so it was rank 54. The 1969 S had fewer coins minted than the 1965 P so it was ranked 55 with the 1965 P being ranked 56 even though they all had the same quantity. The coin with the lowest amount minted had the lower likely of being in my count so, in case of ties, the year with the lowest amount minted was given the next available rank.
