Which one is rarer to find, finding a 2000s cobra head, colonial style post top, or NEMA head in MV, or finding one in MH?

I’ve seen what appear to be late 90s or early 2000s AEL 125’s or GE M400’s in 400W MH on Stringtown road. But, is it rarer to find a 2000-2007 production Mercury vapor light or a metal halide light from the same era? I live in a city that has mostly HPS (and increasingly LED). Columbus plans to swap everything for LED in 2027. There are pretty much no MV street lights around except for old area lights (and, I don’t think we even have newer NEMA’s in MV, I think most of the ones with NEMA tags are HPS).

I’m only referring to lights on streets and city or state-owned lights, not lights on private property because we all know MH is everywhere in parking lots, canopy lighting, as well packs, and formerly indoor lighting (before the move to fluorescent and LED). Is it rarer to find a mercury vapor light from the 2000s or a metal halide light on a utility-owned pole? Because, in the 2000s, they normally installed high pressure sodium. I know that Toledo and Cleveland used MV’s until around the ban for spot replacements. I know Cincinnati, OH used metal halide to replace MV (in the 90s or 2000s) and I think sometimes for new installations. But, which one is rarer to find?

At least in the US I’ve never seen a MH NEMA in the field (if those are what you’re referring to), so I’d say those are rarer.

What about for cobra heads and four sided colonial lanterns (TC-100, Lexington, Traditionaire, model 247).
