I am getting a new ledger put together this weekend to record my coin purchases and am curious what others do for this. I tried to make a spreadsheet on the computer just to have a saved outline with the columns set up but am going back to my old favorite pen, ruler, and 11x17 paper. I like having it all in a binder with the invoices and handwritten notes. It is interesting to go back and review that stuff from time to time. I will have columns for date purchased, denom, year, variety, grade, obv/ rev notes, price paid, etc. Please share what you all do for ledgers!
