You can use gold to buy items from a vendor or other players, transfer gold to other player characters, bid with gold for an item at the Auction House. Other uses are to buy additional bag slots at the bank or hunters can buy stable slots for their pets from a stable master. Players can obtain classic gold by completing quests, killing monsters, selling items to vendors, via trade or mail from other player characters, or by selling an item at the Auction House. I will list many easy ways to earn gold in wow classic.
Here are some specific ways to make yourself some money in the vanilla version of World of Warcraft!
Buy Low Sell High on the Auction House
This has been the most common strategy to farm gold over the lifespan of World of Warcraft. This can be a long term strategy, however, so if you need gold right away, then you might want to consider some of the other options.
What you want to do is gather up enough gold to purchase both the Shadowfang and Assassin's Blade from the Auction House. These will be flooding the market because of how many people will be playing the game in the early stages of the launch. You can then, hopefully, sell those in a couple of months when the surplus of items has gone down and the demand has gone up. This should net you a pretty tidy profit, but again this is a more long term play.
To go further with this, you can use a couple of addons for the Auction House. Both Auctioneer and Aux will help you figure out what you can purchase that's below market value, and will give you a chance to sell them for a higher price!
Mage Only: Sell Portals, Conjured Food Drink
When people are grinding out their levels they will be hoping to cut down on the time spent traveling around Azeroth. If you're a Mage, you can charge people some silver to Portal them to their next location! You can do this by sitting in the main hub city (Stormwind for Alliance Orgrimmar for Horde). You can also conjure stacks of food and drink and sell that to players. Just charge less than what it would cost to purchase it at a vendor!
Fishing
Fishing is one of the more lucrative professions, and one everyone can get. It's something you'll want to level up, because fish you can catch like Stonescale Eel and Nightfin Snapper sell very well on the Auction House because they are both used by raiders in either potions or for food.
Nightfin Snapper
Nightfin Snapper is used in the recipe Nightfin Soup which is used by healers to not only restore health but mana as well. The fish can only be caught at night, from 6pm to 6am in whatever your server time is. You can find them in the following locations:
Feralas (Horde): Camp Mojache
Un'Goro Crater: North of Fire Plume Ridge (River)
Eastern Plaguelands: Outside of Stratholme
Azshara: Lake Mennar
Stonescale Eel
The eels are used by Alchemists to create Stonescale Oil, which is then used to create valuable potions like the Flash of the Titans. You will need to be at least 205 skill to catch these, and they are best farmed at night. You can find them in the following locations:
Azshara: Bay of Storms
Tanaris: Steamwheedle Port
Hinterlands (Horde): Revantusk Village
Feralas (Alliance): Feathermoon Outpost
Jadefire Farm Run
This is a farming method that involve collecting an item you will need if you are a caster in raids, but will also net you some pretty sweet gold. You will need to go to Felwood and to the places circled on the map below.
These areas have a bunch of satyrs that are part of the Jadefire clan. If you're a raider, they drop Demonic Runes which can be used to recover mana at a cost of your health. You are likely going to need to farm these regardless, so it's worth your time to hit these spots. The other thing they drop is Felcloth, which is a hot item for Tailoring. Not only is it used for the Felcloth Bag, it's also used to create certain Warlock items that are quite powerful. This cloth sells very well on the Auction House, so farming it plus gaining runes will kill two birds with one stone.
Grinding Whelps
If you're looking to get a bunch of leather, reagents for raids, and possibly a rare pet, then grinding whelps is for you! You can go back at 60 and grind these, or you can add these to your leveling experience and make some gold along the way. These whelps drop Small Flame Sacs, which can be used to craft Dragonbreath Chili (Cooking), Fire Protection Potion (Alchemy), and Flame Deflector (Engineering). Each type of whelp listed below can also drop a Whelpling Pet that can sell for a lot of gold on the Auction House. Keep in mind that the pet is very rare, it's around a 1 in 1,000 drop rate. So, don't count on getting one of those unless you are super dedicated to the grind.
Crimson Whelps (Levels 25-26)
You'll find Crimson Whelps in the Wetlands. You'll want to be level 26+ to kill them efficiently, but higher is better for speed. They can drop the Tiny Crimson Whelpling pet!
Dreaming Whelps (Levels 35 - 36)
Dreaming Whelps can be found in the Swamp of Sorrows. You'll need to be level 36+ to kill these efficiently. This is a pretty popular spot, so you might not be alone in the area unless you leveled up pretty fast or are on a smaller server. They have a possibility of dropping a Tiny Emerald Whelping pet.
Scalding Whelps (Levels 39-40)
Scalding Whelps are over in the Badlands, and will require you to be around 40+ to take these down efficiently. This is probably going to be less popular than the Swamp of Sorrows location. The Dark Whelpling Pet is a possible drop from these.
