Something with Steel Bars
Special thanks to Oeste06 for this tip!
Requirements
Able to mine coal and iron
Able to smith steel bars
Make a full invitory of steel bars and go to the Rimmington house portal. You can sell them to POH (Player Owned Houses) owners (like myself :-D) for 500 gp each. Well, I probably wouldn't buy because I'm low on cash. Lol.
