5. FAQ
Is 10 K gold real gold?

Register early – 90 days out often has the lowest tier – or volunteer for a local event, which can earn you a free entry.
Can I sell a 10 K chain for melt value?
Pawn shops and refineries typically pay 50-90 % of melt, depending on weight and their service fee. Collect at least three quotes before selling.
