It's a coin from boss event. You need to collect 250 coins to get a tittle. Or get 30 gold coins from hope 02. You will get 1 coin when boss will be killed and take reward from hope 02. Hope 02 apears when boss is killed.

You may drop those silver coins from lv 41+ when you beat the majin mob that appear randomly when you beat normal mobs. They're linked to the "Boss" Quest (you should have the icon in the bottom right of your screen). Once every 8 days, really strong Bosses appear around the map of Mushroom rocks (Both N and S, depending on your level), once players beat one of them, a robot appears. He will give you the prize for the Boss Quest and you can buy a couple of things from him using those Silver and Golden Coins ;)

From Left to right: 1.-Craft item? 2.-Teapot? 3and4.-Papers for what? 5.-Milk to open door at rp2?
6.-White Stuff? 7.-Two Purple Scrolls from FlyQuest (complete) that I touch and nothing happens?
8.-Pink Stuff?
