Sweating & clipping coins

[DaBoss]

Two old techniques for extracting valuable metals out of coins, without impacting their use as currency. In short, sweating is where a coin is placed in a bag and friction is used to grind metal off the coin, where it collects in a pile of dust at the bottom of the bag. Clipping is where you literally cut a piece of the coin off. These techniques have been used across history and across the world anywhere that has valuable metals in their coins, and is a major reason why coins nowadays tend to be made of much cheaper metals. But in space they still use gold and silver coins...

Sweating I dunno, maybe something to do with dice bags or money bags (put them through a washing machine while in a bag?). Clipping would be done with wirecutters. This would give you a sliver of material and remove the same amount of material from the coin. Clipped or sweated coins have a chance of failing to give you credits when you put them in an ID.

The amount of material in coins makes it difficult to actually make this worth doing, but I think it's still a fun enough idea.
