This guide contains general tips on how to make currency farming endgame maps plus a quick suggested build that works pretty well with the ideas presented.
Introduction
This guide contains as concisely as possible the build that I use to farm at the start of a league when I have almost no currency whatsoever, alongside some general farming tips and thoughts that you might or not agree with. Take the parts that you think are good, change or discard the ones that you don't and have fun.
Mapping
One of the best ways to accumulate currency is to simply keep doing low tier maps while focusing on selling complete sets of unidentified equipment for the 2c vendor recipe. The reasons why this is effective are several:
You can have an overleveled character with item rarity/quantity gear that will clear the area pretty easily without any drop rate penalties;
In theory the 2 regal recipe is worth more than the 2c one, but in practice you'll probably have to do a 1:1 rate if you want to sell them fast;
Although the idea of finding that dream 20ex kitchen knife or any other high price equipment may sound appealing, PoE's drop system works very much like a lottery, this meaning that one of these items will most likely drop in the league, but most likely it won't be for you;
Good-but-not-so-good rare items are hard to sell even when undercutting the prices, you'll probably just end up with whole stashes of rare items that won't sell;
Currency drop rate does not increase in higher tier maps;
When running the maps you should always use an Orb of Alchemy on them, at the very least you'll get you alchemy back in drops and most of the time you'll profit.
To maximize your gains, you should do as often as possible maps that drop high value divination cards. These may change from league to league, so you should take a quick look at PoE's wiki.
Although this may be a little obvious, you should do the labyrinths inside the maps, as they drop offerings, which sell for around 4~6c each.
You should get a good item filter before starting farming and keep your eyes open for items that sell for the 7x Jeweller's Orb and 1x Chromatic Orb recipes.
Don't identify any maps you find, since you get a bonus in item rarity and quantity for doing an unidentified map.
Strongboxes
It is recommended that you always carry with you a pack of Transmutation Orbs, Alteration Orbs, Augmentation Orbs and Vaal Orbs for rerolling strongboxes. You may also need a Scouring Orb from time to time to clear a bad rolled rare strongbox that you find on maps, so it might be a good idea to carry a pack of these too in order to avoid wasting map portals.
You should reroll Arcanist's Strongboxes, Artisan's Strongboxes and Diviner's Strongboxes until you get a "of Abundance” (+x additional items) or "of Bounty” (% increased quantity of contained items) suffixes.
You should reroll Cartographer's Strongboxes until you get one of the two suffixes already mentioned, but you should also corrupt it with a vaal orb afterwards. This will give you high rarity/quantity corrupted maps.
I personally like to reroll Jeweller's Strongboxes until I get a "of Affluence” (x additional rare items) suffix to help with the 2c recipe, but you can also use the same strategy of the Cartographer's Strongboxes to try to get some really good corrupted jewellery, although this works best at higher tier maps.
Stash Management
It really helps a lot if you can buy a 8 stash tab pack and at least 1 premium stash to organize the items you take and your trading. It is a good idea to keep a tab for each type of equipment of the 2c recipe, one for helmets, another for rings, amulets and belts, another for boots etc. Since the jewellery (rings, amulets and belts) tend to be the bottleneck of this recipe, once you fill the tabs of the other pieces you can just ignore their drops for a time or identify them if you want.
As you farm, if your stash is being filled with maps and you need to free up space, you can use a transmutation orb on 3 equal maps and vendor them for a higher tier unidentified magic map, which gets a pretty decent item rarity/quantity, close to a bad roll with an alchemy. Another option is to do the Chisel recipe.
Trading
There are few items that are really worth putting for trade and, as said above, it helps a lot if you can get a premium stash tab for doing this. Mainly you should trade:
High value divination cards: you should check the price on poe trade and possibly undercut depending on volume;
High value uniques: same as above. If an unique is only selling for 1fus/alch or 1c you're better off just vendoring it;
Quality gems: the ones that are worth trading are the ones with at least 10~13%. As a rule of thumb you should ask for 1c per point of quality, but this may vary from skill to skill and you may want to do a lower price to attract buyers for a quick sale. You should keep the low quality ones for the GCP recipe;
Any good rares that you think will be sold fast;
Popular gems at the league;
If you want make a little extra with trading, you can also put for sale a whole bunch of assorted "normal” gems with a highly undercut price of 2 jeweller's or so. A good portion of them sell like you wouldn't believe. If you follow this guide, you should be able to accrue currency and high-level loot at a rather swift and efficient pace.
