Melt them down into ingots and sell to gnomes. They are always tinkering with something to make a steampunk mechanical device , and copper tubing is usually involved.
@KorvinStarmast I did sort out the mass of that many coins at some point. I wonder if the commodity value of the copper exceeds the value of the individual coins. DM economics problems.
@ColinGross We used to melt down silver pieces and have them made into silver sling stones (OD&D/AD&D) 10-12 per stone. Useful against undead. Not sure if 5e rolls that way, the "silvering of ammunition" at 100 GP is a bit of a 'horsepoopie" way to handle sling stones. All you need is a mold.
@KorvinStarmast For manufacturing silver ammunition. Creative. I like it. You also need a furnace or charcoal to heat it up. Some handling tools would probably be nice. Blacksmith tools would cover it all ?
@ColinGross To melt silver, you need flame that it pretty hot (1700 deg F) though not quite as hot as a forge for working swords. (Jewelers don't need the kind of heat the blacksmith does, IIRC).
@Grosscol Your question is based on an unfounded premise, which is that there is "magical damage" as a type. There isn't. Pure magical damage is called force damage. Also, not a contradiction, and exception, and Sun Blade need not ever drop in a game. All magic items are DM options. That exception is handled by Specific over General.
I added some of that into the answer.
The attack is magical, or it isn't. What kind of damage is smite? Radiant, right?
@Grosscol Colin, I think that the confusion comes from reading a JC tweet that was in response to a fighter question, and applying it to Rogue. Since the devs have said that they didn't balance the game for MC, and they are not making UA with MC in mind, crossing the streams seems to be a confusing thing.
