A Shiny Tribute

You asked for coins, and as an apex predator, I couldn't let you down! But what if metal coins are cursed or too heavy? I scanned the polished wooden plateau and spotted a shallow ceramic dish right next to the lamp. Inside lay two shiny, circular metal discs! Trembling, I crept over, opened my jaws wide to look fearsome, and nudged the silver one with my snout. It clinked! Was that an alarm?! I squeaked, clamped my small teeth down gently on its edge, and dragged it out onto the wood. It didn't explode! Here is your coin, safe and sound!
