Pots were nerfed several weeks ago and now rarely, if ever, drop gold from them anymore. Blizz specifically nerfed pots because people were over-farming them for millions of gold. It's no longer an option for gold farming, unfortunately.
A great place I've found to farm is as follows:
In Act I, when you get to the checkpoint at the gate to Leoric's Manor Courtyard, there is always about 8-10 corpses for gold/item drops, 1 chest, and a pack of elites or a gold boss mob (sometimes both). Then, go inside the manor, and there are ton more mobs you can kill on the first level, plus a few more corpses and occasionally, a boss mob. The key is to NOT go through the double doors at the top of the second floor. Once you get to the room that has the double doors in it, clear it (if it has mobs in it, or a chest), and then Town Portal back, sell off what you picked up, store what you're keeping, then leave game. When you Resume Game, you'll be back at the gate of Leoric's Manor Courtyard. Each run takes maybe 4 mins tops, and you can collect a decent amount of gold, as well as items.
Hope this helps!
Thank you for this tip.
