Coins.
Get spawns coins in Lumbridge or just attack goblins for coins.
Don't hack, you cheater. Please earn the coins yourself if you can.
Rune coins can be purchased through the official Runescape site. On the top navigation bar simply hover over shop, and then click on the solomons store. There you can follow the prompts and purchase rune coins!
see the RS knowledge base.
no such thing lol :)
30,000 coins.

the only way to get any trimmed armour in runescape w/o paying coins is by treasure trails. you can only do these if your a member:)
5 coins on RuneScape is practically nothing. You can pick up some ashes and sell them, at about 50 coins each; or you can mine clay and get about 5000 coins per trip (in about 5 minutes). Those items must then be sold on the Grand Exchange.
by doing quests and selling finding and stealing items
