Food for thought---
For those of us that have many molds:
how many have you used in the last week, month, year, 5 years, EVER?
How many do you use regularly
IF you are like me you have a handful of "go-to molds" you've developed sub MOA loads for.
Like most of us, I've bought a fair selection of new / custom molds, I've also bought/traded for collections of molds many of which I've never used or don't have guns for.
To get any kind of return on a mold, especially "custom molds" ie NOE, Accurate, MiHec --- you have to find an AVID caster who wants/needs the mold most average caster will never pay the price even for what a used "custom mold" is worth.
Unless you know the seller well or get a chance to try the mold, there are no guarantees to the instability of a used mold regardless of how it looks.
Guess what I'm saying is it's hard to extrapolate the value of a used mold and even harder to find a buyer for what you think it's worth. --- My 2 ¢
I have an Exel spreadsheet for my: rifle molds, Pistol molds, and black powder molds.
Most of these molds have been cleaned, oiled, wrapped in VPI paper, labeled and stored in HF multiple bin storage cases, and tucked away in a filing cabinet.
YES, I should sell many of them but I have the disease that many casters have --- I may get a gun that needs that mold
