2020 Niue Woman Warrior Valkyrie 2oz Antique Finish Silver Coin. This is one of the coolest series devoted to all of the great women warriors overtime and this series is still going. The first release was the Amazon. This is the second release and this is coin number 84 out of 555. To my knowledge it’s the first one that has an actual wood insert for the shield. Once again, you can never go wrong with the mint of Poland. Metal: Silver (Ag) 999.9. Date of issue: 2020.
