# Coin and Coins#

A Coin represents a single coin, which is a pair consisting of a denomination and an amount. Coins represents a collection of Coin objects, that many operators use to group tokens in one construct.

import { Coin, Coins } from "@terra-money/terra.js";

const c = new Coin("uluna", 1500000); // 1.5 LUNA
const c2 = new Coin("uluna", 3000000); // 3 LUNA
cs2.map((x) => console.log(${x.denom}:${x.amount}));

const c = new Coin("uluna", 123.3); // a DecCoin

Although it is convenient to represent the numbers through JavaScript’s native Number format, you should refrain from doing so.
