See below my original blog entry for an important update.
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 PostmasterGS for collecting this data and posting it online.
UPDATE: PostmasterGS has revised his stats. Please see his post on the Stamp Community discussion group.
1840-1940 total: 99,766 issues
1840-1940 total mint CV: 31,978,784 €
1840-1940 total used CV: 19,206,986 €
