The prices for weapons, monster and other equipment differs and depend on the particular features (e.g. Size, strength, quality). You can find the prices here in the website: MicroMonster, Armours, Artefacts (the Gold symbol) or at the merchants place in the game. For instance there are many artefacts from 5 Gold and so on.
Sometimes you can be lucky and find a weapon or another piece of equipment. These items are for free.
