Currently I manage my coin collection with some excel file with one-country-one-sheet sistem with some visual basic scripts I wrote for help. Collection is growing larger and larger and maybe it's time to change this sistem...
So I decided to test CS and maybe to use it in future.
But I don't see how could in CS handle duplicates.
Let me explain (example): I have COIN, released in year 2001, which is coin in my collection. Also have duplicates of that coin (same km#), released in years 2001 (2 pcs.), 2002 (4 pcs.), 2005 (3 pcs.) and 2008 (1 piece). How do I smart write this COIN in my collection on CS: so one coin in collection and more duplicates with different years and pieces?
And how to export only duplicates...?
