I received another gift that was purchased from some app called Shopee. Again, since they were bought online, I'm having doubts about the coin's authenticity. I'm thinking that it's real, though, considering the corrosion and the consistency of the design and measurements listed in the coin's Numista page (https://en.numista.com/catalogue/pieces3173.html). However, I always seek more opinions so I'm 99.9% sure.


The diameter (measured through calipers) is 18.85 mm. The thickness is consistent with its non-steel counterpart.
(Also, yes, I'll definitely change the coin flip when my order arrives.)
Any relevant input is very much appreciated. Feel free to move this post to a more appropriate section of the forum if it does not fit here. Thank you!
