You can't, the only way you can get another is by transfering it from another game, sorry.
The amulet coin is in castelia city there are 3 dancers (Pokemon trainers) and if you defeat all 3 at the fountain the one in the middle will give you the amulet coin. The trainers have pansage, pansear and panpour.
I can trade you one if you want.
yes
You go to the Guy in the shack in West Lumbridge Swamp and Ask him for a new one.
go 2 one of those buildings between the route and the city, there's lots of them but only some have stairs. find one with stairs and go up the stairs, if there's a scientist there talk 2 him he might be the one who gives u amulet coin. if not find another scientist on 2nd floor of a route-city building and see if he gives u amulet coin. also the guy who gives u amulet coin won't give u amulet coin till u catch a certain no. of pkmn, he will tell u how much pkmn 2 catch.
you can get it from one of the aides if you have about 40 Pokemon collected
You get the amulet coin by bringing a "cute" Pokemon into amity square andgoing to the old ruins. then you go inside the left one and take 2 steps forward then one to the left. Don't move and press A. you should get it.
Either its the big building to the left of celadon city or the one left of fuchsia city but at the top of the building an Oak Aide will give you an amulet coin if you registered 40 Pokemon in your pokedex.
The amulet coin is an item to be held by a Pokemon. It doubles the prize money you receive from battles with other trainers if the Pokemon holding it takes part in the battle. Note however if more than one Pokemon holding an amulet coin fight in the battle the prize money will still be only twice the original prize money i.e. multiple amulet coins do not stack.

when u have 50 pokemon go to one of the proffesors aids and he will give you
Go left of celadon city go in the big building go upstairs talk to oak's aide if you have 50 or more Pokemon in your pokedex you get a amulet coin.
The only ways to make money are: Winning battles and selling items and goods.If you have beaten the league, i'd say the best place to get money is on resort goregeous, with the two ladies. If you have amulet coin, one of them gives you 200 000 and the other gives 19600. if you dont have amulet coin, well, do the math! Divide it by two.Now if you haven't beaten the league, just go to your good training spot, and use amulet coin so you get double the money!Hope it helped!P.S I think you get amulet coin on the left of celadon city, in that weird mini house that leads to cycling road. Or was it the one on Fuchsia?
