A week ago, I decided I should start tracking my collection to some extent - at least those coins I have decided were worthy enough to put into binders. I know there are a lot of software tools that are designed to do this best, but I found that a simple spreadsheet in excel did the trick for me. I created columns for country (because most of my collection is foreign), denomination, year, grade (my opinion), metal content, bullion value (I created a formula for automatically calculating this based on a single cell, where I can put in the current values of gold and silver), book value, whether I had a scan picture, and finally any notes about the coin worth mention. Over the past week, I have managed to ctalague nearly 500 coins. So does anyone else keep an electronic file of their collection?
