Question: what are the chances of getting a golden crate in terraria?
Answer: As an example, fishing with a Fishing Power of 100 in a lake of at least 300 valid water tiles in the Corruption would yield crates with the following probabilities: Golden Crate: 1/150 (0.67%); Corrupt Crate: 7/750 (0.93%); Iron Crate: 7/250 (2.8%); Wooden Crate: 7/125 (5.6%). The Crate Potion doubles these chances.
