While it won't earn you loads of Gold Bars overnight, you'll likely be able to rack up a handful of Gold Bars if you're a regular player. Thankfully, odds are you'll pick up Gold Nuggets in Red Dead Online simply by playing. However, once you've earned 100 Nuggets, they will automatically be turned into a Gold Bar. Unfortunately, the Gold Nugget to Gold Bar ratio is pretty low, as it currently sits at 100 Gold Nuggets = 1 Gold Bar. In Red Dead Online, Gold can be found in the form of Gold Nuggets. Gold can be found in Red Dead Online by looting enemies, completing Story missions, completing Stranger missions, playing Showdown Modes, and participating in free roam events. Additionally, if you link your Rockstar Social Club account with your Twitch Prime account, you can get 15% on your first purchase of Gold Bars.
Gold Bars can be purchased in the Red Dead Online Store.
