Wow. They look Celtic to me, the central decoration on the left hand item is familiar although I can't find a picture. The spoke and boss shape is similar to Celtic rouellles: Celtic Coins Ancient Coins Rouelles MA Coin stores with 500.000 Coins and Medals - German Coins and Ancient Coins, World. The item on left is also similar to one type of celtic strap unions: Celtic Coins Ancient Coins Rouelles MA Coin stores with 500.000 Coins and Medals - German Coins and Ancient Coins, World
