Selected title: Trial
Explanation: Usually as in 'trial piece', any coin often including patterns, made in a different metal from the normal production metal, and produced to test the dies or preview the design. Lead is often used as it is very soft, and trial pieces are normally struck before the dies are completed and hardened, so that minor changes can still be made before the dies are hardened
