Heh. Thank you for the info. I hate algebra. For my general purpose for my spreadsheet I will just use the numbers listed in Charlton's and from this site. I do not think anyone who views the spreadsheet will comment if my 2007 - 2010 mintage are wrong or any other mintage for that fact. I'm trying to figure out what else I can put in my spreadsheet. I'm new to Excel and learning as I go. Any ideas of what else would be useful for my spreadsheet? I'm using to keep track of how many coins I have. I tracks Date, Quantity, Mintage, Variety, Error, Composition, Weight, Diameter and a generalized Pictures for each year to show the OBV and REV with a picture showing Varieties/errors. It is still a work in progress and I have the Canada Small cents done and a start on nickels 1922 +. Looking to see what other information other people like to track. I will work on individual coin grades and pictures in the not to distant future.
Any ideas would be appreciated.
