Well, after some years of experience you would be able to understand which domains will have a limited attractive (let's say: end-users and brandable domain names, can convert into nice sales but it requires an active marketing) and which one will have a high attractive (like LLL.com or pronounceable LLLL.coms or powerful generic .com domains).
After you have divided your domains into these two groups, i think you could list the less attractive domains with BIN price in several marketplaces (but be sure to not disperse them everywhere, limit yourself to 3 or max 4 marketplaces, like Sedo, GD, Flippa and another one), because it's extremely unlikely you'd find two BIN buyers at the same time, and list the more attractive ones with Make an Offer only. You might add a BIN price in only one of the marketplaces.
Just remember to remove the sold domain from the other marketplaces as soon as you complete the sale.
A good practice, if unexperienced, would be list all the domains on the marketplaces (again, max 3 or 4, plus your own website) with the "make an offer" option only, no BIN. After a while (months, at least) you will eventually realize if you have attractive domains or not, according to the views and the offers, and divide them in groups properly.
Years ago it happened to me to have listed a domain on Sedo with a mid $xxx BIN but being contacted through email by a potential buyer who offered me $1,xxx for the domain after few negotiations. He didn't search for the domain on marketplaces (or even google), just did a whois and contact the registrant email . At the meantime i didn't think to remove the domain from there (or at least remove the BIN price).
Right after the end of the negotiations, while i was preparing the Escrow, the domain has been sold through Sedo at BIN. After some insults to myself, to karma, to life in general, i had to accept my mistake, and emailed him about the cancellation of the sale because of inconvenients or whatelse, don't remember correctly.
He was very polite and kind.
Then i figured out the Sedo buyer was him.
