Nobody answers. Please check the new price at the internet. https://www.midwayusa.com/ is a good place to start. Then depend upon how long the tools/materials used and/or how clean they are, I would put price of 30%~80% of the new. Just my suggestion.
I watched the Red Hornady reloading machine in front of me and recollect those days that I enjoyed making pistol and rifle ammos. I can't spare my time to do that again. Hew!
I've been there. Put the whole die into freezer. Since the brass, lead, stainless steel all have different thermal expansion coefficients, they will start to separate by a little force. Repeat several times if necessary.
Recently I moved from Virginia. It's funny that MD and VA were enemies just 100 years ago. I am glad to join Maryland Shooters. I still miss the NRA musium and the 50 yard underground range nearby.
