Silver for currency

I think someone suggested to have Silver Ore added in the game but didn't state the purpose for it. So here's my idea. With Silver Ore, it can be smelted and turned into Silver Ingot. A Silver Ingot can either be used by using it along with emeralds as currency. It also has the same rarity as emeralds but is a lot more common at Y level -51. Can be found with a vein of 4-5 ores and drops 1 silver ore. Can be crafted into nuggets and can also be used in trading for seeds on a Farmer villager.
