They are stackable even if you don't note them.
Sorry but I'm afraid you cant re-use gold charms on Runescape, but however you'd be glad to know they are stackable.
Slayer usually gets it
All kinds of food are stackable.
Almost every Monster Drops Gold Charms but you can receive multiple charms from the level 111 Giant Rock Crab in the Chaos Tunnels.
You get charms by monster drops.
No one in Runescape sells gold charms or any other charms for that matter as they are untradeable, but many monster drop them like ogres by Castle Wars or the monster in the Legend's Dungeon. Do you slayer task you should get lots. Charm drop rate vary from every monsters in Runecape. __ You can receive one free gold charm from "pikkupsticks" in the Taverly summoning store/building.
