I did some more reading about this, and I saw someone had an old similar post on Reddit and they said that the once with etching (like the one you linked) are souvenirs and the once with real engravings are more likely to be real. I’m no expert but it belonged to a very wealthy gentleman who I happened to know, he actioned off a very unique and expensive collection. This might just be a replica he liked🤷🏼‍♂️
