Hi there!
I don't know if this topic have been discussed before but we should have only one banknote type per page and under that type we should have all the different variants, years, dates, etc. Here is an example of what I consider is a mistake: Argentina 1 Peso. In this page there are two different banknotes listed: P-287 and P-293, Those are very similar but different notes. The 2019 Standard Catalog of World Paper Money 1961-Present lists them as two separate and different notes and the same principle should be follow in Numista.
I'd like to get your opinion about this.
Regardss,
