I wrote back in 2017 about a collector who had created a database of Michel catalog information for every country that you could sort by years, country, etc. The compiler has recently updated the information to use 2018/2019 catalog data.
The website can be found at: https://www.germanstamps.net/ia-cost-comparison-ww/
Since Michel no longer makes the data available, this will be the last update.
I think it is well worth visiting the site, and playing with the various filters. But, to get to the bottom line, based on Michel catalog data, there were 66,609 stamps issued between 1840 and 1940 with a total catalog value for used copies of about 14.5 million Euros.
Kudos to Postmaster GS for collecting this data and posting it online.
