Why its shown on the 10 escudos (https://en.numista.com/catalogue/pieces5444.html) coin's main features that the coin began to be struck in 196 instead of 1969? The 196 variant is a date error on a trial strike, ok to show it on the years list, but showing this on the main profile is causing it to appear incorrectly when you search coins by date. And that's how I found it: searched for all older coins in my collection by typing 0-1800 in the date tab and it appeared (obviously it shouldn't be on that search result).
Thanks in advance for who looks on this issue.
