Is there a world silver cheat sheet?

I am currently working on a 20th century circulating world silver coin spreadsheet noting the country ASW and other essential things with what in the end should be close to 1500 coins.
I have seen others on other websites but not ones that have been this complete, If you know of one similar to what mine should be, please let me know, and assuming I finish I will post it here but it will take awhile.
