Problems about the mintage of 100 drachmes coin of Greece

The 1990 100 drachmes coin of Greece (https://en.numista.com/catalogue/pieces568.html) was minted only for 949,000 pieces, but look at them for exchanging for this coin, they are many! (https://en.numista.com/echanges/liste.php?piece=568) So, fix this!

I wonder where the Numista contributor found the mintage numbers for this type -
Kraus declines to list mintages for any of the years, which suggest no reliable figures are available.

edit to add: This thread should be moved to the Numista Catalog section, as is addresses a problem with the catalogue.

With all due respect why is the number of people who want to exchange a coin a reason to think a mintage is wrong? What else would you do with this coin now that Greece adopted the euro?
It might be wrong, but the USA had a similar issue in the Jefferson nickle series. The 1950 D is the series key. When it came out, it was horded. And so now there are an unbelievably number of them available and in very hi grade. I would leave it alone unless reliable sources indicate a larger mintage.

regardless of the availability in the market, Reliable Sources i.e. The Standard Catalogue and NGC refuse to print any mintage for all years of this type, so can the referee please provide the source of the numbers in Numista.

Referee might not be able to do that, since it might not be possible to establish who added the mintage and from where.

Maybe another idea to keep the source comment for every change made in a coin page

​If possible on the Bank of Greece (https://www.bankofgreece.gr/Pages/default.aspx), find the mintage of the 100 drachmes coin of Greece in 1990.
