Serious question about a title belt and a reality show!!

[PRIDE OF BOSTON]

Here is one with Malignaggi and it isn't engraved though

Here is Wlad and his doesn't look engraved....

Maybe they used to? Maybe they just engrave it after you relinquish it? or lose it?

The WBO is engraved..

That makes sense. You know, I even looked up the Spinks(Michael and Leon's) Olympic runs after seeing the medal in front of the IBF belt in the shop thinking that could shed some light on it but they were in the Olympics in the 70s and that's an '84 medal.
