Depends on what classes.
If you have a generic farmer featherfoot build. Do 260 and get a shot at your Intasurta Gloves. Solo full runs using JP>Swell net you 2mil for 30mins spent with your multiply tokens.
If you want to burn even faster and you have a character that runs and guns like a Limacon Reiter. Hit one of the dungeons with very high mob count. 170 was the standard in the past (barring any nerfs I haven’t heard about). That you’ill want to do a test run with silver monitor addon to confirm there weren’t changes to silver drops.

A lot of your farm rate depends on the gear and types of damage rotations you’re doing. Especially for nukers that have heavy cooldowns. So using the farmed app and timing your DG clears is your best course of action.
And keep a students mind when you’re doing your clears. Often you can come up with ways to improve your time if you think of a clever skill/pull rotation least if you’re using CDs. Like in the example of featherfoot. There are parts of the 260 that are all melee. And you can do pulls with single swell or double swell into blood suck without bothering to use joint penalty and you can burn your swells more effectively that way.
