how much could I sell magnetized bare models for? like what percent

About tree fiddy

Unless it's something very complex (all Baneblade variants magnetised on one chassis or something), I'd say you'd struggle to even get 75 percent of retail value.

The moment you break the seal on the box expect to get no more than 70% MSRP

Everything you do to it from there will only decrease its value.

Flavor of the month models well assembled and primed might fetch 60% MSRP, but models for things not in the meta, or very commonly bought models that everyone has, expect around 40% MSRP.

If you've "pro painted" it, I personally would not pay more than 10% to 20% MSRP unless it was something really uncommon that I really wanted.

This is all different for metal models. Those tend to be worth more because it is far easier to remove paint. Out of production metal models sometimes go for as much as 200% MSRP (especially for old models), but usually hover around 100% MSRP from what I've seen. Really old collectible models can go for lots and lots. I've heard of people paying 50 bucks for a Johnny.

Last I check RT era plastics were around 12 dollars per sprue of two marines if the sprue still had everything on it and in good condition. Given their age, that resale value isn't great.
