I use multiple Excel spreadsheets.
1) Overall US and Canadian collection totals
* Tracks how many of each date/mintmark/variety of each denomination (currency included) I have in my collection
* Also tracks how many I am looking for of each date/mintmark/variety of each denomination.
* Gives percent complete for each series.
2) Foreign coin collection totals
* Very basic for now, just how many of each I have by country/denomination/year
3) 2008 Trip Report
* Tracks which bank I went to on which day
* What I did at each bank (cashed in or purchased)
* Results of every purchase including how many of each error I searched for or other categories that I track.
4) Total Found in 2008
* Tracks how many of each date/mintmark/variety that I found (only for ones I keep)
5) 2008 TNet Group Tracking List
* Use this to keep track of the tracking list thread.
6) 2008 Personal Tracking List
* Similar to #5, except only tracks what I personally found.
7) Lifetime Personal Tracking List
* Also similar to #5, except it is what I personally found over my lifetime (at least what I can verify that I found)
#4, #5, #6, and #7 are essentially the same spreadsheet with different data.
If anyone wants a blank copy of any of these spreadsheets, just pm me a non-TNet email address that can handle the size. Note: Zipped up these files will likely be over 1 MB total, but I think they will be under 2 MB unless the size changes drastically with the improvements I made for 2008.
** Update ** Just cleaned up the files a bit and zipped up the three main ones and it turns out it is only 682 KB.
