You would get the most money by putting things that go together in lots (like: all 9mm bullets) and selling each lot individually.
This is also the most work, and the most interactions.
The easiest route, that gets less money (maybe half as much or less) is to sell the entire lot to a single person who has use for some of it, and is willing to flip the rest. That buyer might end up with everything they want from your lot for “free” after they put in the work of parting it out.
We can help you fairly price any individual lot, individual item, or the whole lot. Note that some items will never sell on their own. Not enough juice for the squeeze, as they say.
If it were my lot, and I knew nothing about pricing at all, I’d sell to people here who will treat you fair.
If I wanted to do more work and maybe make a bit more, I’d buy a table at the next big gun show and see what I could make off the people there. Then I’d come back here and sell the remainders as a single lot.
I can easily make out over a thousand dollars worth of stuff in the pics. It’s worth more than 1K, but there’s 1K that I see I could use. At least most of it is not obscure caliber items.
