As title says this is personally my first fake slab, heard about these before but have been yet to see one.
Pretty well packaged there was some signs of the slab being glued together rather than ultrasonic(which i think is how they normally do it)
Seller/maker of fake slab have used a coin with an older UIN that does not show a picture of the coin but along with that they obviously didn't have a copy of the correct barcode(above UIN) which if scanned using the mobile app should redirect you to the pcgs verification page for this exact coin, which it actually redirects you to a silver dollar worth $200000
Coin appears to also not fit correctly in the middle portion and this also appears to be badly tooled and tooling scratches still on it.
Coin looks alright, no expert but , very good copy, if anything if it was a real coin it would grade higher than MS63 so another thing that was a bit off about this.
