I found a coin with Gustaf VI Adolf with a date of 1956 and in the denomination of 2KR, what's it worth?

A 1956 Swedish 2 Kronor contains 0.18 troy ounces of silver which is currently worth about $2.80US, and the coin retails for $4.50US or more if like new. By the way, "GUSTAF VI ADOLF SVERIGES KONUNG" means (Adolph Gustaf VI King of Sweden). “PLIKTEN FRAMFÖR ALLT” is the king's motto, and it means (Duty First). Adolf Gustaf VI was king of Sweden from 1950 until 1973. I hope that helps.
