Thank you for very helpful advise!

We are thinking it will take up to a year

Hello, I am a new here, so sorry if I am in wrong place. For a serious project with my grandson I am looking for data of geographical distribution of coins findings that I think can be considered as a characteristic of trade connections. What we want to do is to create a map of finding of certain coin(s) of certain country in other countries. Coin type, country of origin and even time of mint not matter much for a moment (or at least it seems so). We would greatly appreciate any advise about how we can collect this type of data. Preferably it should be a database (databases) of coins with geographical data (preferably in a form of longitude-latitude) of their findings. Many thanks in advance.
