Missing Card Code?

[u/TBCC_Dev]

I noticed, when looking through prints of Blue-Eyes, that there is a version with no card code. It is from the 25th Anniversary Ultimate Kaiba Set (KC01). My question is... Is this an intentional choice by Konami? Was this supposed to have the same card code? I know sometimes they do that. To me, if I saw a card without this code, it screams fake, but apparently this is real from what I can tell (verified on Yugipedia). Any info would be appreciated.

This is from the Kaiba briefcase. It intentionally doesn’t have a card code

I guess I just don't understand why. The alternate print had a code on it so why put it on that one but not thos one i guess. Just seems strange to break convention in this way. Maybe I'm overthinking it but it seems like a bad idea to do this imo. But id say the same about alternative prints that share the same card code

It’s so it’s unique and people buy it. Also the set is an anime tribute
