Hi,
I'm just putting some 50 francs and 100 francs coins a side and have found the following errors in numista:
50 Francs
1972 - 2014 https://en.numista.com/catalogue/pieces1798.html: from 2012 the coins are fe-ni, and I doubt they also exist in ni, so 2012-13 & 14 are too many in that article
2015-now https://en.numista.com/catalogue/pieces53891.html: seems OK
100 Francs
1967 - 2009 https://en.numista.com/catalogue/pieces1372.html: from 2006 the coins are in fe-ni and I doubt the coins from 2006-07 and 09 were made in Ni, so those years should be deleted:
2012 - now https://en.numista.com/catalogue/pieces53892.html: actually this article should include the coins from 2006 to date, since they are all magnetic!
That's it.
Ole
