Your gold price depends on what kind of gold you have. Nuggets, coins and bullion have quite different prices.
I think most people overestimate the value of their gold jewelry. To be pure gold, it would be 24caret, which isn’t going to happen. Class rings? Forget it. Mine were only 10 caret. That’s about 42% purity, and most rings don’t weigh that much.14 caret gold? 58%. Besides that, it’s important to have a buyer who won’t rip you off. It’s important that people are aware of the actual value of what they’re purchasing, or they’ll be ripped off both buying and selling.
