These are the current bellums on the market, and this is what it says under "Get Estimated Price":



The lowest one is currently 500, but on the get estimated price window, it says 1k.

It internally calculates a rating for the weapon and looks up (the same)tiers/weapons with a similar(similar as in, there is a set margin it can look for below and above your weapons calculated rating to determine price) rating stored in the market (suffixes/traits get added to this rating as well) to determine the estimate price. The one that is 1k has a better chance, so I'm assuming your bellum also has a better chance that a 1 in 10.

If you have a really good version of the tier, a really bad version will not affect the estimated price.
