Mexican libertads

[CollectorNo1]

Hi

I'm guessing someone will have the answer to this.....the diameter and thickness on the 2oz silver proofs seem to change on the same date coins...

I was looking to purchase a couple and they were a 2018 and 2019...the thickness differs from 3mm to 4.5mm - diameter 40 and 48mm?

When I googled this..it states the 2oz proof silver is 40d and 3mm thick...

 

What am I missing.. would appreciate any advice

Regards

Are you positive that one is not a 5 oz Libertad?

And did you measure? Pictures please if you are able. Counterfeit? 

A bit of a puzzle, that.

Hi

Havnt recd it yet as only purchased yesterday. I was looking at another 2oz silver proof 2018 and in the description it had 48mm diameter  and 4.5mm thickness so out of curiosity I googled the libertad, the trouble is there were conflicting descriptions for the 2oz libertad...e.g some saying 40mm and 3mm others saying 48mm 4.5mm. And they were both 2oz.

I've attached photo of the one I've purchased.
