Gold value at 22 karat is around $120 US. But since it's a unique nugget probably around $300 US. Most gold found in nature is around 22 karats.

Oof, that's worth more than I thought!
Seems like a great activity to do with friends / kids every now and than! :D

Gold nuggets always carry a premium price, it's best never to sell them to collectors who will appreciate them!
