Quote: "ngdawa"Like I said in this topic, the locking of year lists is more a hindrance to prevent the catalogue to easily grow and become better, than what it stops error in non-existing dates getting added..
I must disagree with you on that--I have ended up rejecting quite a few "add a new year-line" requests. From what I have experienced, the requests are typically dates on a different page. The two major exceptions are if the coins are extremely modern, or if the year-list is genuinely not complete (as in, it is missing quite a few year-lines).

Anyways, back to the coin in question: in 2018, Romania added a crown atop the eagle's head, which gives all the 2018 coins their own page. The one in question is located here:
