The Idea is to add a second value field besides buying value.
Why?
To have a better way to calculate the valuation of the collection.
1/ most of us have coins that was obtained as heritage or, like me, are form countries were the currency used to buy it no longer exits/high inflation, so the current buying value is Zero.
2/ some times we find a good deal and pay less than it's worth.
3/ some time we pay a premium, which is usually the case of us outside US/Europe.
So that's the idea.
Today I put that value at a comment field and then create a new column on excel to calculate
If anyone has a solution, particularly when exporting to excel, I'll appreciate to know
thanks
