I can.
There's several ways to secure a nugget.
1. Save up money to buy one from the market. They may be as cheap as 5k or much more expensive, depending on the age of your server.
The best way is to go to world chat, an ask for a someone to sell a cheap nugget. Don't be dismayed if you don't attain success on your first try. There are hundreds of people on your server at different times, so it may not be the first time you ask, but eventually someone will sell one to you.
An alternate way is to ask an alliance member. None of em have a nugget for you? Join a new alliance.
2. Use gold coins to procure a nugget. Don't recall the price in gold coins of a nugget, but whatever it is, it's not worth it. I suggest trying method 1 until it works.
3. Harvest a nugget from a hunt. Not getting into details, but there's a hunting guide that may be able to help you to this extent. Here's the link:

Uhhhhh, don't hold your breath on this one. I'd try method 1 before this one.
5. Find one in a box. It may be very very likely that you open either a god box or a silver box and find a nugget, but then it would have been less coins to just get a nugget outright from NPC.
Hope this helps you. In the end, you'll find nuggets aren't hard to come by, even if they are now. Be patient, have good luck, and happy hunting!
